In addition, the authority level of each user ID is different, and the privacy of the corresponding call recording files is also different. If a call recording file with a higher privacy is leaked, it may cause certain property losses. For example, if a call recording file in the financial industry is leaked, it may cause property losses. Therefore, user ID analysis, text conversion, type analysis, and user ID authority analysis are performed on the call recording files to be managed, so as to achieve orderly management of the call recording files to be managed, while avoiding the leakage of important call recording files and reducing property losses.

[0023] Reference Figure 2 As shown, based on the file management terminal, the metadata of the call recording and the audio data of the call recording are analyzed and processed, and the audio data of the call recording of the same user ID is obtained, which specifically includes the following steps: S201, based on the file management terminal, extracting and processing the metadata of the call recording to obtain the user ID information of the call recording; S202, based on the file management terminal, performing correlation analysis on the metadata of the call recording and the audio data of the call recording to determine correlation information of the call recording; S203, based on the file management terminal, classify the audio data of the call recording based on the user ID information of the call recording and the association information of the call recording as features, and determine the audio data of the call recording with the same user ID; In this embodiment, in order to achieve orderly management of call recording files to be managed, the metadata of the call recordings is analyzed to determine the user ID information of the metadata of each call recording, that is, the user ID information of the call recording. Then, the audio data of the call recordings is classified and processed according to the user ID information of the call recordings, and the audio data of the call recordings with the same user ID is determined. Subsequently, the audio data of the call recordings with the same user ID is stored in a folder to achieve orderly management of the call recording files to be managed.

[0024] Reference Figure 3 As shown, based on the file management terminal, analyzing and processing the file header information of the call recording and the audio data of the call recording with the same user ID, and obtaining the text information of the call recording with the same user ID specifically includes the following steps: S301, based on the file management terminal, read and process the file header information of the call recording to obtain parameter characteristics of the audio data; S302, based on the file management terminal, performing parameter analysis on parameter features of the audio data to determine a processing method for the audio data; S303, based on the file management terminal, audio data of the call recording of the same user ID is preprocessed based on the processing mode of the audio data, and the preprocessed audio data of the same user ID is obtained, wherein the audio preprocessing includes audio denoising and blank audio deletion; S304, based on a natural language processing algorithm, performing text conversion on the pre-processed audio data of the same user ID to obtain text information of the call recording of the same user ID; In this embodiment, if the header file information of an audio data is unknown, the audio data cannot be analyzed and processed, because the header file information of the audio data contains the format, encoding method, etc. of the audio data. Therefore, in order to pre-process and convert the audio data of the call recording of the same user ID into text, it is necessary to analyze the file header information of the call recording to determine the parameter characteristics of the audio data, and then analyze the parameter characteristics of the audio data to determine the processing method of the audio data. Finally, the audio data of the call recording of the same user ID is pre-processed and converted into text according to the processing method of the audio data.

[0025] Reference Figure 4As shown, based on the file management terminal, the text information of the call recordings with the same user ID is analyzed for type, and the type of the call recordings with the same user ID is determined, which specifically includes the following steps: S401, based on the file management terminal, performing feature extraction processing on the text information of the call recording of the same user ID to obtain the keyword features of the call recording; S402, based on the file management terminal, weight calculation processing is performed on the keyword features of the call recording to determine the keyword weight data; S403, based on the file management terminal, the keyword weight data is sorted by maximum value to determine the call recording type of the same user ID; In this embodiment, to determine the type of audio data of a call recording with the same user ID, it is necessary to analyze the audio data to determine the content recorded in the audio data. Therefore, by performing feature analysis on the text information of the call recording with the same user ID, keyword features of the call recording are screened out. The keyword features of the call recording, for example, the same verb features, noun features, etc., the keyword weight data is determined according to the proportion of the same verb features and noun features in the text information of the call recording with the same user ID. The largest keyword weight data is the type of the text information of the call recording with the same user ID.

[0026] Reference Figure 5 As shown, based on the file management terminal, the call recording type and metadata of the call recording of the same user ID are analyzed and processed to determine the call recording folders of the same type, which specifically includes the following steps: S501, based on the file management terminal, classify and process the audio data corresponding to the call recording type of the same user ID to determine the call recording data of the same type; S502, based on the file management terminal, metadata retrieval is performed on call recording data of the same type based on the associated information of the call recordings as a feature, and metadata of the call recordings corresponding to the call recordings of the same type are determined; S503, based on the file management terminal, performing information extraction processing on the metadata of the call recordings corresponding to the same type of call recordings, and obtaining date information of the same type of call recordings; S504, based on the file management terminal, sorting the call recording data of the same type based on the date information of the call recordings of the same type as a feature to obtain ordered call recording data; S505. Based on the file management terminal, a folder is constructed based on the call recording type of the same user ID as a feature and the ordered call recording data is stored in the corresponding folder to obtain a call recording folder of the same type; In this embodiment, even if the audio data corresponding to the call recording type of the same user ID are stored together, confusion may occur because the audio data of the same type of call recording may exist on different dates. In order to make it more convenient to extract the audio data of the call recording on a specific date, the call recording data of the same type are sorted again according to the date information of the call recordings of the same type, and stored in the call recording folder of the same type, so as to further realize the orderly management of the call recording files to be managed.

[0027] Reference Figure 6 As shown, based on the file management terminal, the user ID corresponding to the same type of call recording folder is analyzed for permissions, and the private user and the public user are determined, which specifically includes the following steps: S601, based on the file management terminal, performing data reading and processing on the database system to obtain the authority level classification standard of the user ID; S602, based on the file management terminal, performing permission matching processing on the user IDs corresponding to the same type of call recording folders and the permission level classification standard of the user IDs to determine the permission level of the user ID; S603, based on the file management terminal, judging the authority level of the user ID and setting the authority level threshold; S604: If the authority level of the user ID is less than the set authority level threshold, the user corresponding to the authority level of the user ID is a public user; S605: If the authority level of the user ID is greater than or equal to the set authority level threshold, the user corresponding to the authority level of the user ID is a private user; In this embodiment, the audio data of call recordings corresponding to different user IDs may contain audio data of call recordings with higher privacy. If the audio data is leaked, certain property losses may occur, such as audio data in the financial industry. In addition, some audio data also have certain legal effect, such as audio data in the insurance industry. Therefore, it is necessary to perform authority analysis on user IDs, such as the ID information of practitioners in the insurance industry or the financial industry.

[0028] Reference Figure 7 As shown, based on the file management terminal, private users and public users are analyzed and processed, and different encryption methods are selected, which specifically includes the following steps: S701, if the user ID corresponding to the call recording folder of the same type is a private user; S702, based on the encryption algorithm, encrypting the call recording folders of the same type owned by the private user; S703, if the user ID corresponding to the call recording folder of the same type is a public user; S704, based on the file management terminal, performing privacy analysis on the call recording data in the same type of call recording folders owned by the public user, and determining the same type of call recording folders that need to be encrypted; In this embodiment, when it is determined that the user ID corresponding to the same type of call recording folder is a private user, in order to avoid the leakage of the audio data of the call recording, all the audio data of the call recording is encrypted. Even if the audio data of some call recordings is not very important, there is no guarantee whether the user mentioned any industry information during the call. Therefore, all the audio data of the call recordings are encrypted. However, the audio data of the call recordings of public users are not unimportant. The audio data of some call recordings is also important, such as the information of the company. Even if the user is not a financial practitioner, the information of his company may be important, so it needs to be encrypted.

[0029] Reference Figure 8 As shown, based on the file management terminal, the call recording data in the call recording folders of the same type owned by the public user are analyzed for privacy, and the call recording folders of the same type that need to be encrypted are determined, specifically including the following steps: S7041. Based on the file management terminal, extract the text information of the call recordings of the same user ID based on the public user ID information, and obtain the text information of all the call recordings of the public user; S7042. Based on the file management terminal, data is read and processed from the database system to obtain a private keyword comparison table; S7043. Based on the file management terminal, match the text information of all the call recordings of the public user with the private keyword comparison table to obtain the number of private keywords in the call recording folder of the same type; S7044, based on the file management terminal, analyzing and processing the information on the number of private keywords in the call recording folders of the same type, and determining whether to encrypt the call recording folders of the same type; In this embodiment, in order to filter out the audio data of the call recordings that need to be encrypted, the text information of all the call recordings of the public user is filtered through the private keyword comparison table. The private keyword comparison table records keywords of types such as company and property. When this type of keyword appears in the text information of all the call recordings of the public user, it needs to be encrypted and protected.

[0030] Reference Fig. 9 As shown, based on the file management terminal, analyzing and processing the private keyword quantity information in the same type of call recording folders to determine whether to encrypt the same type of call recording folders specifically includes the following steps: S70441. Based on the file management terminal, determine and process the number of private keywords in the call recording folders of the same type and set the threshold of the number of private keywords; S70442, if the number of private keywords in the call recording folder of the same type is greater than or equal to the set private keyword number threshold, encrypt the call recording folder of the same type based on the encryption algorithm; S70443. If the number of private keywords in the call recording folder of the same type is less than the set private keyword number threshold, the call recording folder of the same type is a public folder and is not encrypted; In this embodiment, if the number of private keywords in the call recording folder of the same type is less than the set private keyword number threshold, that is, the text information of all the call recordings of the public user does not contain the words in the private keyword comparison table, it means that the audio data of the call recording of the user will not cause property loss, so it does not need to be encrypted.
