For example, two blocks or steps shown in succession may be performed substantially simultaneously or in reverse order, and in some cases, some blocks or steps may be omitted.

[0014] FIG. 1 is a diagram illustrating the structure of an English translation service provider server that provides an English translation service for Korean lyrics according to an embodiment of the present invention.

[0015] Referring to FIG. 1, the English translation service providing server (110) according to the present invention includes a lyrics translation unit (111), an English lyrics generation unit (112), a converted lyrics generation unit (113), a converted musical score generation unit (114), an English translation musical score generation unit (115), and a musical score data transmission unit (116).

[0016] The lyrics translation unit (111) receives data regarding the score of the first music from the user terminal (130) held by the user, and when an English translation request command requesting the translation of Korean lyrics into English is received, it generates English lyrics by translating the Korean lyrics mapped to the score into English through a pre-built translation engine.

[0017] Here, the musical score consists of n measures (n is a natural number greater than or equal to 8), and in the musical score, Korean lyrics are mapped to corresponding notes syllable by syllable.

[0018] The English lyrics generation unit (112) generates English lyrics corresponding to each of the n nodes by matching English lyrics corresponding to Korean lyrics mapped to each node for each of the n nodes.

[0019] When English lyrics corresponding to each of the n nodes are generated, the converted lyrics generation unit (113) generates converted lyrics corresponding to each of the n nodes by converting the pronunciation of the English lyrics for each node into Korean for each of the n nodes.

[0020] When a converted musical score generation unit (114) generates a converted musical score, for each of the n measures, the converted lyrics corresponding to each of the n measures are generated, and the characters constituting the Korean lyrics mapped to each measure are sequentially replaced one by one with the characters constituting the converted lyrics for each measure.

[0021] At this time, according to one embodiment of the present invention, the converted score generating unit (114) may include a verification unit (117) and a first replacement unit (118).

[0022] The verification unit (117) checks whether, in the first node which is one of the n nodes, the number of characters constituting the converted lyrics exceeds the number of characters constituting the Korean lyrics, and in the first node, the number of characters constituting the converted lyrics is k times (k is a natural number greater than or equal to 2) times the number of characters constituting the Korean lyrics.

[0023] In the case where it is confirmed that the number of characters constituting the converted lyrics in the first section is less than k times the number of characters constituting the Korean lyrics, for the first section, the remaining characters excluding the first character of the last syllable among the characters constituting the Korean lyrics are sequentially replaced one by one with the characters constituting the converted lyrics for the first section, and then the first character is replaced with the remaining characters that are not replaced among the characters constituting the converted lyrics for the first section.

[0024] In addition, according to one embodiment of the present invention, the converted score generating unit (114) may further include a second replacement unit (119).

[0025] In the case where it is confirmed that the number of characters constituting the converted lyrics in the first section is k times or more than the number of characters constituting the Korean lyrics, the second replacement section (119) calculates a first result value by rounding the quotient obtained by dividing the number of characters constituting the converted lyrics in the first section by the number of characters constituting the Korean lyrics, and then sequentially replaces the remaining characters, excluding the first character of the last syllable among the characters constituting the Korean lyrics, one by one with the number of characters corresponding to the first result value among the characters constituting the converted lyrics for the first section, and then replaces the first character with the remaining characters that were not replaced among the characters constituting the converted lyrics for the first section.

[0026] When the English translation score generation unit (115) generates the English translation score, it generates the English translation score by inversely converting the characters constituting the converted lyrics mapped to the converted score into the characters of the English lyrics corresponding to the pronunciation of each character.

[0027] When the English translation sheet music is generated, the sheet music data transmission unit (116) transmits data regarding the English translation sheet music to the user terminal (130).

[0028] Below, the operation of the lyrics translation unit (111), English lyrics generation unit (112), converted lyrics generation unit (113), converted musical score generation unit (114), English translated musical score generation unit (115), and musical score data transmission unit (116) will be explained in detail with examples.

[0029] First, let’s assume that data regarding the score of the first music titled ‘Nabiya’ (the score is composed of 16 measures, ‘measure 1, measure 2, measure 3, measure 4, measure 5, measure 6, measure 7, measure 8, ...’, and in the score, Korean lyrics are mapped to corresponding notes by syllable, and by referring to the figure shown in FIG. 2, it can be confirmed that for ‘measure 1’ among the 16 measures constituting the score, ‘measure 1, measure 2, measure 3, measure 4, measure 5, measure 6, measure 7, measure 8, ...’, the Korean lyrics titled ‘Nabiya’ are mapped to corresponding notes by syllable, and by referring to the figure shown in FIG. 2, it can be confirmed that the Korean lyrics are mapped to corresponding notes by syllable for ‘measure 1’) is received, and an English translation request command is received requesting to translate the Korean lyrics into English.

[0030] Then, the lyrics translation unit (111) can generate English lyrics as shown in Table 2 below by translating the Korean lyrics mapped to the musical score as shown in Table 1 below into English through a pre-built translation engine.

[0032] Korean lyrics mapped to the above sheet music Segment 1 Butterfly Segment 2 Butterfly Segment 3 Fly here Segment 4 Come here Segment 5 Yellow butterfly Measure 6 white butterfly Segment 7 Dancing Segment 8 Come here ... ...

[0034] English lyrics butterfly, butterflycome and fly on over hereyellow and white butterflycome and dance on over here...

[0036] After that, the English lyrics generation unit (112) can generate English lyrics corresponding to each of ‘verse 1, verse 2, verse 3, verse 4, verse 5, verse 6, verse 7, verse 8, ...’ as shown in Table 3 below by matching English lyrics corresponding to Korean lyrics mapped to each verse for each of ‘verse 1, verse 2, verse 3, verse 4, verse 5, verse 6, verse 7, verse 8, ...’.

[0038] Segment 1 butterfly Segment 2 butterfly Segment 3 come and fly Segment 4 on over here Segment 5 yellow and Measure 6 white butterfly Segment 7 Come and dance Segment 8 on over here ... ...

[0040] Thus, when English lyrics corresponding to each of ‘verse 1, verse 2, verse 3, verse 4, verse 5, verse 6, verse 7, verse 8, ...’ are generated by the English lyrics generation unit (112), the converted lyrics generation unit (113) can generate converted lyrics corresponding to each of ‘verse 1, verse 2, verse 3, verse 4, verse 5, verse 6, verse 7, verse 8, ...’ by converting the pronunciation of the English lyrics for each verse into Hangul for each of ‘verse 1, verse 2, verse 3, verse 4, verse 5, verse 6, verse 7, verse 8, ...’ as shown in Table 4 below.

[0042] Segment 1 Butterfly Segment 2 Butterfly Segment 3 Come and Fly Segment 4 On Over Here Segment 5 Yellow and Measure 6 White Butterfly Segment 7 Come and Dance Segment 8 On Over Here ... ...

[0044] Thus, when a converted lyric corresponding to each of 'measure 1, measure 2, measure 3, measure 4, measure 5, measure 6, measure 7, measure 8, ...' is generated by the converted lyric generating unit (113), the converted musical score generating unit (114) can generate a converted musical score by sequentially replacing the characters constituting the Korean lyrics mapped to each measure with the characters constituting the converted lyrics for each measure one by one for each of 'measure 1, measure 2, measure 3, measure 4, measure 5, measure 6, measure 7, measure 8, ...'.

[0045] At this time, in 'No. 1', which is one of the 16 above-mentioned 'No. 1, No. 2, No. 3, No. 4, No. 5, No. 6, No. 7, No. 8, ...', since the number of characters constituting the converted lyrics 'Butterfly' exceeds the number of characters constituting the Korean lyrics 'Nabi-ya', the verification unit (117) can check whether the number of characters constituting the converted lyrics 'Butterfly' in 'No. 1' is k times or more than the number of characters constituting the Korean lyrics 'Nabi-ya'.

[0046] In this regard, when 'k=2', it is confirmed that the number of characters '5' constituting the converted lyrics 'Butterfly' in 'Segment 1' is less than twice the number of characters '3' constituting the Korean lyrics 'Nabi-ya'. Therefore, the first replacement part (118) can replace 'Na' among the characters 'Na, Bi', which are the characters constituting the Korean lyrics 'Nabi-ya' in 'Segment 1', excluding 'Ya', which is the first character of the last syllable, with 'Beo' among the characters 'Beo, Teo, Fl, La, I', which are the characters constituting the converted lyrics 'Butterfly' for 'Segment 1'.

[0047] Then, the first replacement part (118) can replace 'bi' among the remaining characters 'na, bi' with 'ter' among 'ter, ple, la, i'.

[0048] After that, the first replacement part (118) can replace the first character 'ya' with the remaining characters 'fl, la, i' that were not replaced among the characters 'butter, plo, la, i' that make up the transformed lyrics for 'butterfly' for 'segment 1'.

[0049] In this way, the first replacement part (118) can sequentially replace the remaining characters, excluding the first character of the last syllable among the characters constituting the Korean lyrics for 'segment 1, segment 2, segment 3, segment 4, segment 8, ...', with the characters constituting the converted lyrics for each segment, and then replace the first character with the remaining characters that were not replaced among the characters constituting the converted lyrics for each segment.

[0050] Additionally, regarding 'segment 6', since it is confirmed that the number of characters '8' constituting the converted lyrics 'White Butterfly' is more than twice the number of characters '3' constituting the Korean lyrics 'White Butterfly', the second replacement part (119) can produce a first result value such as '3' by rounding up the quotient '2.6' obtained by dividing the number of characters '8' constituting the converted lyrics 'White Butterfly' by the number of characters '3' constituting the Korean lyrics 'White Butterfly' for 'segment 6'.

[0051] Then, the second replacement part (119) can replace ‘White’ among the remaining characters, ‘White, Na’, excluding ‘Bi’, the first character of the last syllable, among the characters that make up the Korean lyrics ‘White Butterfly’, with ‘White, I, T, Beo, Teo, Fl, La, I’, which make up the converted lyrics for ‘Segment 6’, with the number of characters, ‘White, I, T’, among the characters that make up the first result value, ‘3’.

[0052] After that, the second replacement part (119) can replace 'Na' among the remaining characters 'White, Na' with the characters 'Bu, Ter, Fl' among 'Bu, Ter, Fl', which correspond to the number of characters '3' of the first result value.

[0053] Then, the second replacement part (119) can replace the first character 'B' with the remaining characters 'Ra, I' that were not replaced among the characters 'Hwa, I, T, Beo, Teo, Fl, La, I' that make up the transformed lyrics for 'Segment 6', 'White Butterfly'.

[0054] Thus, the converted score generating unit (114) can generate a converted score as shown in Table 5 below by sequentially replacing the characters constituting the Korean lyrics mapped to each measure with the characters constituting the converted lyrics for each measure one by one for each measure, and when the number of converted lyrics is greater than the number of Korean lyrics, by performing character replacement through the first replacement unit (118) and the second replacement unit (119).

[0056] Conversion score Segment 1 me friend rain place hey Fly Segment 2 me friend rain place hey Fly Segment 3 this Com lee Ann me play ah lie Segment 4 oh on you oh la Berhere Segment 5 paddle Yellow with as me right rain Ann Measure 6 white white me Butterfree rain lie Segment 7 dance Com second Ann weight Dan as S Segment 8 oh on you oh la Berhere ... ... ...

[0058] Thus, when a converted musical score as shown in Table 5 is generated through the converted musical score generation unit (114), the English translation musical score generation unit (115) can generate an English translation musical score as shown in Table 6 below by inversely converting the characters constituting the converted lyrics mapped to the converted musical score into the characters of the English lyrics corresponding to the pronunciation of each character.

[0060] English translation of the sheet music Segment 1 friend bu place tter Fly fly Segment 2 friend bu place tter Fly fly Segment 3 Com come Ann and play fl lie ly Segment 4 on on oh o Berhere verhere Segment 5 Yellow yel as lo right wu Ann and Measure 6 white white Butterfree butterfl lie ly Segment 7 Com come Ann and Dan dan S ce Segment 8 on on oh o Berhere verhere ... ... ...

[0062] After that, the sheet music data transmission unit (116) can transmit data for the English translation of the sheet music to the user terminal (130).

[0063] According to one embodiment of the present invention, the English translation service may be provided as a paid service. In addition, since data regarding musical scores is often subject to copyright, it is necessary to take measures to ensure that only the user who requested the English translation of the musical score can receive the English translated score.

[0064] Accordingly, the present invention may further include a security configuration to ensure that only users who have paid a predetermined service usage fee or users who have requested an English translation based on the original score due to copyright issues can receive the English translated score.

[0065] Specifically, a method may be used in which data regarding an English translation of a musical score is provided to a user in an encrypted form, along with a password for decryption, and when the user attempts to decrypt the encrypted data, the user is requested to transmit the previously issued password, and if the password is successfully replied to by the user, a decryption key for decrypting the data is provided to the user.

[0066] According to one embodiment of the present invention, as a specific configuration for such security processing, the score data transmission unit (116) may include a pseudo-random number generation function storage unit (120), an encryption transmission event generation unit (121), a pseudo-random number generation unit (122), an operation matrix generation unit (123), a hash value generation unit (124), an encryption unit (125), and an encryption transmission unit (126).

[0067] The pseudo-random number generation function storage unit (120) stores t different (t is a natural number greater than or equal to 2) pseudo-random number generation functions that are pre-set.

[0068] Here, pseudo-random numbers refer to random numbers generated by a predetermined random number generation algorithm.

[0069] For example, if t is assumed to be '2' and two different pre-set pseudo-random number generation functions are assumed to be 'pseudo-random number generation function 1, pseudo-random number generation function 2', the two pseudo-random number generation functions, 'pseudo-random number generation function 1, pseudo-random number generation function 2', may be stored in the pseudo-random number generation function storage unit (120).

[0070] When the English translation score is generated, the encryption transmission event generating unit (121) generates an encryption transmission event to encrypt data for the English translation score and transmit it to the user terminal (130).

[0071] When the above encryption transmission event occurs, the pseudo-random number generator (122) randomly generates a password of u (where u is a natural number of 2 or more digits), sets the number of measures constituting the musical score as a seed value for pseudo-random number generation, and then applies the seed value as an input to each of the t pseudo-random number generation functions stored in the pseudo-random number generation function storage unit (120) to generate t pseudo-random numbers.

[0072] When the t pseudo-random numbers are generated, the operation matrix generation unit (123) generates a u-dimensional column vector having each digit constituting the u-digit password as a component and a t-dimensional row vector having each of the t pseudo-random numbers as a component, and then generates an operation matrix of size uxt by performing a matrix multiplication between the column vector and the row vector.

[0073] When the operation matrix is ​​generated, the hash value generation unit (124) generates a connection number by concatenating the components constituting the operation matrix in ascending order, and then generates a first hash value by applying the connection number as input to a preset hash function.

[0074] When the first hash value is generated, the encryption unit (125) generates encrypted data by encrypting the data for the English translation score with the first hash value.

[0075] When the encryption transmission unit (126) generates the encryption data, it transmits the encryption data to the user terminal (130) and generates and transmits a guidance message to the user terminal (130) indicating that the u-digit password is a password for decrypting the encryption data.

[0076] Hereinafter, the operation of the encryption transmission event generation unit (121), the pseudo-random number generation unit (122), the operation matrix generation unit (123), the hash value generation unit (124), the encryption unit (125), and the encryption transmission unit (126) will be explained in detail with examples.

[0077] First, let u be '4' and let the English translation score be generated by the English translation score generation unit (115). Then, the encryption transmission event generation unit (121) can generate an encryption transmission event to encrypt data for the English translation score and transmit it to the user terminal (130).

[0078] Thus, when the encryption transmission event is generated by the encryption transmission event generating unit (121), the pseudo-random number generating unit (122) can randomly generate a 4-digit password such as '8275'.

[0079] After that, the pseudo-random number generator (122) can generate two pseudo-random numbers such as '11' and '10' by designating '16', which is the number of measures constituting the musical score, as a seed value for pseudo-random number generation, and then applying the seed value '16' as an input to each of the two pseudo-random number generation functions, 'pseudo-random number generation function 1' and 'pseudo-random number generation function 2', which are stored in the pseudo-random number generation function storage unit (120).

[0080] Thus, when the two pseudo-random numbers are generated by the pseudo-random number generator (122), the operation matrix generator (123) generates a 4-dimensional column vector having each digit constituting the 4-digit password '8275' as a component, ' 'and, a 2D row vector having the two aforementioned pseudo-random numbers '11' and '10' as components, respectively After generating ', the above column vector ' ' and the above row vector ' By performing matrix multiplication between ' You can create an operation matrix of size 4 x 2 such as '.

[0081] Then, the hash value generation unit (124) is the above operation matrix ' By concatenating the components that make up '88, 80, 22, 20, 77, 70, 55, 50' in ascending order, a concatenated number such as '2022505570778088' can be generated.

[0082] After that, the hash value generation unit (124) can generate a first hash value such as '26d103c620a31345ag57qat327891703' by applying the aforementioned concatenation number '2022505570778088' as input to a preset hash function.

[0083] Thus, when the first hash value is generated by the hash value generation unit (124), the encryption unit (125) can generate encrypted data by encrypting the data for the English translation sheet music with the first hash value, '26d103c620a31345ag57qat327891703'.

[0084] Thus, when the encrypted data is generated by the encryption unit (125), the encryption transmission unit (126) can transmit the encrypted data to the user terminal (130) and, while doing so, generate and transmit a guidance message to the user terminal (130) indicating that the 4-digit password '8275' is the password for decrypting the encrypted data.

[0085] According to one embodiment of the present invention, the English translation service providing server (110) may further include a password request unit (127), a hash value restoration unit (128), and a decryption key transmission unit (129).

[0086] The password request unit (127) requests the user terminal (130) to transmit the password issued to the user, after the encrypted data and the guidance message have been transmitted to the user terminal (130) and a decryption command for the encrypted data is authorized by the user on the user terminal (130). When a request command for the transmission of a decryption key for decrypting the encrypted data is received from the user terminal (130), the password request unit (127) requests the user terminal (130) to transmit the password issued to the user.

[0087] When the hash value recovery unit (128) receives the u-digit password from the user terminal (130), it sets the number of measures constituting the musical score as the seed value, applies the seed value as input to each of the t pseudo-random number generation functions stored in the pseudo-random number generation function storage unit (120) to generate the t pseudo-random numbers, generates the u-dimensional column vector having each digit constituting the u-digit password as a component and the t-dimensional row vector having each of the t pseudo-random numbers as a component, generates the operation matrix by performing matrix multiplication between the column vector and the row vector, generates the concatenation number by concatenating the components constituting the operation matrix in ascending order, and then applies the concatenation number as input to the hash function to generate the first hash value.

[0088] When the first hash value is generated, the decryption key transmission unit (129) transmits the first hash value to the user terminal (130) as a decryption key for decrypting the encrypted data.

[0089] At this time, when the user terminal (130) receives the first hash value from the English translation service provider server (110) as a decryption key for decrypting the encrypted data, it can restore the data for the English translation score by decrypting the encrypted data with the first hash value.

[0090] Below, the operation of the password request unit (127), hash value restoration unit (128), decryption key transmission unit (129), and user terminal (130) will be explained in detail with examples.

[0091] First, let us assume that the encrypted data and the guidance message are transmitted to the user terminal (130) by the encryption transmission unit (126) as in the example described above.

[0092] At this time, when a decryption command for the encrypted data is applied to the user terminal (130) by the user, and when a request command for the transmission of a decryption key for decrypting the encrypted data is received from the user terminal (130) to the English translation service provider server (110), the password request unit (127) may request the user terminal (130) to transmit the password issued to the user.

[0093] In response to this, when the above 4-digit password '8275' is received from the user terminal (130) to the English translation service provider server (110), the hash value recovery unit (128) can designate '16', which is the number of measures constituting the musical score, as the seed value, and then apply the seed value '16' as an input to each of the two pseudo-random number generation functions, 'pseudo-random number generation function 1' and 'pseudo-random number generation function 2', which are stored in the pseudo-random number generation function storage unit (120), to generate the two pseudo-random numbers such as '11' and '10'.

[0094] Thus, when the two pseudo-random numbers are generated by the hash value recovery unit (128), the hash value recovery unit (128) generates the four-dimensional column vector, which is '8275', a four-digit password, having each digit constituting the password as a component 'and, the 2D row vector having the two pseudo-random numbers '11' and '10' as components, respectively After generating ', the above column vector ' ' and the above row vector ' By performing matrix multiplication between ' The above operation matrix can be generated as shown above.

[0095] Thus, when the operation matrix is ​​generated by the hash value recovery unit (128), the hash value recovery unit (128) generates the operation matrix, which is ' By concatenating the components that make up '88, 80, 22, 20, 77, 70, 55, 50' in ascending order, the above concatenated number such as '2022505570778088' can be generated.

[0096] After that, the hash value recovery unit (128) can generate the first hash value such as '26d103c620a31345ag57qat327891703' by applying the concatenation number '2022505570778088' as input to the hash function.

[0097] Thus, when the first hash value is generated by the hash value restoration unit (128), the decryption key transmission unit (129) can transmit the first hash value, '26d103c620a31345ag57qat327891703', to the user terminal (130) as a decryption key for decrypting the encrypted data.

[0098] At this time, when the first hash value is received from the English translation service provider server (110) to the user terminal (130) as a decryption key for decrypting the encrypted data, the user terminal (130) can restore the data for the English translation score by decrypting the encrypted data with the first hash value, '26d103c620a31345ag57qat327891703'.

[0099] Through this, the user can check the English translation of the sheet music.

[0100] FIG. 3 is a flowchart illustrating the operation method of an English translation service provider server that provides an English translation service for Korean lyrics according to an embodiment of the present invention.

[0101] In step (S310), data regarding a musical score of a first piece of music (the musical score consists of n measures (n is a natural number greater than or equal to 8), and in the musical score, Korean lyrics are mapped to corresponding notes syllable by syllable) is received from a user terminal held by the user, and when an English translation request command is received requesting to translate the Korean lyrics into English, English lyrics are generated by translating the Korean lyrics mapped to the musical score into English through a pre-built translation engine.

[0102] In step (S320), for each of the n nodes, English lyrics corresponding to each of the n nodes are generated by matching English lyrics corresponding to Korean lyrics mapped to each node.

[0103] In step (S330), when English lyrics corresponding to each of the n nodes are generated, for each of the n nodes, the pronunciation of the English lyrics for each node is converted into Korean, thereby generating converted lyrics corresponding to each of the n nodes.

[0104] In step (S340), when a transformed lyric corresponding to each of the n measures is generated, a transformed musical score is generated for each of the n measures by sequentially replacing the characters constituting the Korean lyrics mapped to each measure one by one with the characters constituting the transformed lyrics for each measure.

[0105] In step (S350), when the converted musical score is generated, the characters constituting the converted lyrics mapped to the converted musical score are inversely converted into the characters of the English lyrics corresponding to the pronunciation of each character, thereby generating an English translation musical score.

[0107] At this time, according to one embodiment of the present invention, step (S340) may include: a step of checking whether, in a first node which is one of the n nodes, the number of characters constituting the converted lyrics exceeds the number of characters constituting the Korean lyrics, the number of characters constituting the converted lyrics in the first node is k times (k is a natural number greater than or equal to 2) times the number of characters constituting the Korean lyrics; and a step of, in the case where it is confirmed that the number of characters constituting the converted lyrics in the first node is less than k times the number of characters constituting the Korean lyrics, for the first node, the remaining characters excluding the first character of the last syllable among the characters constituting the Korean lyrics are sequentially replaced one by one with the characters constituting the converted lyrics for the first node, and then the first character is replaced with the remaining characters that are not replaced among the characters constituting the converted lyrics for the first node.

[0108] At this time, according to one embodiment of the present invention, in step (S340), if it is confirmed that the number of characters constituting the converted lyrics in the first section is k times or more than the number of characters constituting the Korean lyrics, for the first section, a first result value is calculated by rounding the quotient obtained by dividing the number of characters constituting the converted lyrics by the number of characters constituting the Korean lyrics, and the remaining characters among the characters constituting the Korean lyrics, excluding the first character of the last syllable, are sequentially replaced one by one with a number of characters corresponding to the first result value among the characters constituting the converted lyrics for the first section, and then the first character is replaced with the remaining characters among the characters constituting the converted lyrics for the first section that are not replaced.

[0109] Additionally, according to one embodiment of the present invention, in step (S360), the method comprises: maintaining a pseudo-random number generation function storage unit in which t different (t is a natural number greater than or equal to 2) pseudo-random number generation functions are stored; when the English translation score is generated, generating an encryption transmission event to encrypt data regarding the English translation score and transmit it to the user terminal; when the encryption transmission event is generated, randomly generating a password of u (u is a natural number greater than or equal to 2) digits, designating the number of measures constituting the score as a seed value for pseudo-random number generation, and applying the seed value as an input to each of the t pseudo-random number generation functions stored in the pseudo-random number generation function storage unit to generate t pseudo-random numbers; when the t pseudo-random numbers are generated, generating a u-dimensional column vector having each digit constituting the u-digit password as a component and a t-dimensional row vector having each of the t pseudo-random numbers as a component, and between the column vector and the row vector The method may include the steps of: generating an operation matrix of size uxt by performing matrix multiplication; generating a concatenation number by concatenating the components constituting the operation matrix in ascending order when the operation matrix is ​​generated, and then generating a first hash value by applying the concatenation number as input to a preset hash function; generating encrypted data by encrypting the data for the English translation score with the first hash value when the first hash value is generated; and, when the encrypted data is generated, transmitting the encrypted data to the user terminal while generating and transmitting a guidance message to the user terminal indicating that the u-digit password is a password for decrypting the encrypted data.

[0110] In addition, according to one embodiment of the present invention, the method of operation of the English translation service providing server comprises the steps of: requesting the transmission of a password issued to the user terminal to the user terminal when, after the encrypted data and the guidance message are transmitted to the user terminal, a decryption command for the encrypted data is applied by the user on the user terminal, and when a request command for the transmission of a decryption key for decrypting the encrypted data is received from the user terminal; when the u-digit password is received from the user terminal, the number of measures constituting the musical score is designated as the seed value, and the seed value is applied as input to each of the t pseudo-random number generation functions stored in the pseudo-random number generation function storage unit to generate the t pseudo-random numbers, and after generating the u-dimensional column vector having each digit constituting the u-digit password as a component and the t-dimensional row vector having each of the t pseudo-random numbers as a component, and then generating the operation matrix by performing a matrix multiplication between the column vector and the row vector, and the operation The method may further include the step of generating a connection number by concatenating the components constituting the matrix in ascending order, and then applying the connection number as input to the hash function to generate a first hash value, and, when the first hash value is generated, transmitting the first hash value to the user terminal as a decryption key for decrypting the encrypted data.

[0111] At this time, when the user terminal receives the first hash value from the English translation service provider server as a decryption key for decrypting the encrypted data, it can restore the data for the English translation score by decrypting the encrypted data with the first hash value.
