At the same time, the user's family or friends can also shake their phones to quickly share the pictures or videos.

[0040] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0041] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0042] The information sharing method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0043] like Figure 1 As shown, this application embodiment provides an information sharing method, which is applied to a first electronic device, that is, the method is executed by the first electronic device. Specifically, the method may include:

[0044] Step 101: When the first electronic device performs a shake operation, acquire first information; wherein, the first information includes at least one of the following: first environmental magnetic field change, first timestamp data, and first Bluetooth distance range information;

[0045] Here, the applicable scenario for this application embodiment is: a scenario where a first electronic device and a second electronic device located in the same area as the first electronic device each perform a shake operation at the same time. The number of second electronic devices is greater than or equal to one. The fact that the first and second electronic devices are in the same area indicates that these electronic devices are in the same environment.

[0046] Optionally, multiple electronic devices (including a first electronic device and a second electronic device) establish a first group through their respective users' shake operations. Specifically, this is achieved through the sensors and network technology of the electronic devices, enabling rapid matching of multiple devices. For example, the built-in accelerometer of an electronic device can detect the shaking motion; additionally, to match nearby (within the same area) electronic devices, applications within the electronic devices typically request the device's location information (achieved through GPS, Wi-Fi positioning, or mobile network base stations). Once sufficient information is collected (such as shaking motion, location information, and timestamp information), the application uses a specific algorithm to match nearby users who are simultaneously shaking their electronic devices.

[0047] Step 102: Obtain the first security key based on the first hash value of the first electronic device, the second hash value of the second electronic device, the first information, and the first data feature information corresponding to the shake operation;

[0048] Here, the change in the first ambient magnetic field can be obtained through the geomagnetic sensor built into the first electronic device. It should be noted that the magnetic field information of multiple electronic devices in the same area (e.g., within a distance of ≤10 meters) is very similar. Therefore, information about similar magnetic fields in the same area can be used as one component of the subsequent first security key to enhance the security and randomness of the key.

[0049] It should be noted that the changes in the environmental magnetic field, timestamp data, and Bluetooth range information are unique characteristics of the "shake-to-share" function, which requires multiple people to perform a shake-to-share operation. These three pieces of information limit the "shake-to-share" function to be enabled only when the shake occurs in the same area and at the same time. Specifically, the conditions for "shake-to-share" are that multiple people (≥2 people), in the same area (e.g., distance ≤ 10 meters), and at the same time (e.g., time difference ≤ 15 seconds) shake (move the electronic device) together. Therefore, the first piece of information is used as one of the components of the subsequent first security key to enhance the security and randomness of the key.

[0050] Optionally, the timestamp precision of the first timestamp data is on the order of hundreds of seconds. It should be noted that there may be slight time differences when multiple electronic devices shake their devices "at the same moment". Therefore, the timestamp information of the units and tens digits can be ignored, and the timestamp information of the hundreds digit can be used (i.e., timestamp precision on the order of hundreds of seconds) to ensure that multiple electronic devices use the same timestamp as part of the subsequent first security key.

[0051] Step 103: Based on the first security key, perform symmetric encryption on the first information to obtain the first ciphertext;

[0052] Step 104: Send the first ciphertext.

[0053] It should be noted that the first and second electronic devices located in the same area are both electronic devices involved in the "shake-to-share" function. The changes in the environmental magnetic field, timestamp data, and Bluetooth distance range information are not only unique to the first electronic device but also unique to the second electronic device. Furthermore, the data characteristics of the shake-to-share operation involved in the first and second electronic devices are similar, and the principles by which the first and second electronic devices generate security keys are also the same.

[0054] In this way, the first electronic device generates a first security key based on the hash value of the electronic device, the change in the ambient magnetic field, the timestamp data, the Bluetooth distance range information, and the data feature information corresponding to the shake operation. The second security key generated by the second electronic device based on the hash value of the electronic device, the change in the ambient magnetic field, the timestamp data, the Bluetooth distance range information, and the data feature information corresponding to the shake operation is the same. This ensures that multiple electronic devices generate their own security keys without having to transmit them wirelessly, preventing the keys from being leaked during transmission and thus ensuring the security of information exchange between electronic devices.

[0055] In some embodiments, step 102 above, calculating the first security key based on the first hash value of the first electronic device, the second hash value of the second electronic device, the first information, and the first data feature information corresponding to the shake operation, includes:

[0056] Step 1021: Perform a hash calculation on the user identifier of the first electronic device to obtain the first hash value;

[0057] Here, the user identifier of the first electronic device A can be represented as UIDA. A hash calculation is performed on the user identifier of the first electronic device to obtain the first hash value, which can be represented as: HUIDA = Hash(UIDA).

[0058] Step 1022: Receive the second hash value sent by the second electronic device;

[0059] The second hash value is generated from the user identifier of the second electronic device.

[0060] Here, the user identifier of the second electronic device B can be represented as UIDB. The second hash value can be represented as: HUIDB = Hash(UIDB).

[0061] Step 1023: Perform a hash calculation on the first information to obtain a third hash value;

[0062] In the first information, the first change in the environmental magnetic field is represented by Ma, the first timestamp data is represented by Ta, and the first Bluetooth distance range information is represented by Ra. Here, the first information is hashed to obtain the third hash value, which can be represented as HMTRa = Hash(Ma + Ta + Ra).

[0063] Step 1024: Determine the first locking key based on the first data feature information;

[0064] See Figure 2 This is a waveform diagram showing the data characteristic information of device A and device B. From... Figure 2 As can be seen, the waveforms of the data characteristic information of device A and device B are similar, meaning that the shaking data obtained by device A and device B through the shaking operation are similar.

[0065] As an optional implementation, step 1024 may specifically include:

[0066] The first data feature information is quantized to obtain the first locking key.

[0067] Here, shaking data is obtained through a shaking operation, and first data feature information is extracted from the shaking data.

[0068] Optionally, the first data feature information includes the feature information of the following data: the starting data, peak data, trough data, zero-crossing point data, and ending data of the shaking data.

[0069] Optionally, the first data feature information is quantized to obtain a first locking key, including:

[0070] Based on the first data feature information, a first locking key is determined using a preset quantization rule; wherein the preset quantization rule is:

[0071] If the data is greater than or equal to the positive quantization threshold, then the key corresponding to the data is 1;

[0072] If the data is less than or equal to the negative quantization threshold, the key corresponding to the data is -1;

[0073] If the data falls between the positive quantization threshold and the negative quantization threshold, the corresponding key for the data is 0.

[0074] See Figure 3 This is a schematic diagram illustrating the quantification process of data feature information of device A and device B. Figure 3 The red circle represents the feature data corresponding to device A (i.e., the data included in the first data feature information), and the blue circle represents the feature data corresponding to device B (i.e., the data included in the second data feature information).

[0075] It should be noted that, Figure 3 In the diagram, when the circle (data) falls between the blue dashed line (negative quantization threshold) and the green dashed line (positive quantization threshold), it indicates that the key at that position is 0; when the circle (data) is below the blue dashed line, the key value is -1; when the circle (data) is above the green dashed line, the key value is 1.

[0076] For example, the first electronic device is device A, and the second electronic device is device B, see [reference needed]. Figure 3 The quantization key sequence for device A is [0,1,0,-1,0,1,0,-1,0,1,0], and the quantization key sequence for device B is [0,1,0,-1,0,1,0,-1,0,1,0]. Therefore, the final first locking key KA is [0,1,0,-1,0,1,0,-1,0,1,0], and the second locking key KB is [0,1,0,-1,0,1,0,-1,0,1,0].

[0077] Step 1025: Obtain the first security key based on the first hash value, the second hash value, the third hash value, and the first locking key.

[0078] This step may specifically include: performing a hash calculation on the first locking key to obtain a fifth hash value; and obtaining a first security key based on the first hash value, the second hash value, the third hash value, and the fifth hash value.

[0079] Here, the fifth hash value can be represented as HKA = Hash(KA).

[0080] Specifically, the first hash value is XORed with the second hash value, and then concatenated with the third and fifth hash values ​​to obtain the first security key. That is, the first security key HKeyA = HUIDA. A ⊕HUIDB+HMTRa+HKA.

[0081] As an optional implementation, the method of this application also includes:

[0082] The first hash value is sent to the second electronic device.

[0083] Here, a first hash value is sent to the second electronic device for the purpose of generating a second security key on the second electronic device side.

[0084] In some embodiments, the method of this application further includes:

[0085] Periodically retrieve timestamp data;

[0086] The first security key is updated based on the timestamp data.

[0087] In this embodiment, in order to further enhance the security and randomness of the key, timestamp data is acquired periodically (i.e., periodically). The timestamp data is constantly changing, and the latest timestamp data is acquired periodically. The first information is updated using the timestamp data. Then, the updated first security key is obtained based on the first hash value of the first electronic device, the second hash value of the second electronic device, the updated first information, and the first data feature information corresponding to the shake operation.

[0088] Similarly, the second electronic device also periodically acquires timestamp data and updates the second security key based on the timestamp data. The update cycles for the timestamp data on both the first and second electronic devices are the same, and the updated first and second security keys are identical.

[0089] In some embodiments, the method of this application further includes:

[0090] Receive the second ciphertext sent by the second electronic device;

[0091] Based on the first security key, the second ciphertext is decrypted to obtain the decrypted second information.

[0092] Here, the second ciphertext sent by the second electronic device is the second ciphertext encrypted with the second security key. Since the second security key is the same as the first security key (as can be seen from the above analysis), the second ciphertext can be successfully decrypted based on the first security key, yielding the decrypted second information.

[0093] By using the information sharing method of this application, multiple electronic devices can generate their own security keys without having to transmit them wirelessly, thus preventing the keys from being leaked during transmission and ensuring the security of information exchange between electronic devices.

[0094] like Figure 4As shown in the illustration, this application also provides an information sharing method, which is applied to a second electronic device, i.e., the method is executed by the second electronic device. Specifically, the method may include:

[0095] Step 401: When the second electronic device performs a shake operation, acquire second information; the second information includes at least one of the following: second environmental magnetic field change, second timestamp data, and second Bluetooth distance range information.

[0096] Step 402: Calculate the second security key based on the first hash value of the first electronic device, the second hash value of the second electronic device, the second information, and the second data feature information corresponding to the shake operation;

[0097] It should be noted that the principle of generating the second security key on the second electronic device side is the same as that on the first electronic device side. For details, please refer to the explanation on the first electronic device side, which will not be repeated here.

[0098] Step 403: Receive the first encrypted message sent by the first electronic device;

[0099] Step 404: Based on the second security key, the first ciphertext is decrypted to obtain the decrypted first information.

[0100] Here, the first ciphertext sent by the first electronic device is the first ciphertext encrypted with the first security key. Since the first security key generated by the first electronic device and the second security key generated by the second electronic device are the same (as can be seen from the analysis of the first electronic device), the first ciphertext can be successfully decrypted based on the second security key, yielding the decrypted first information.

[0101] The information sharing method of this application embodiment obtains second information when the second electronic device performs a shake operation. The second information includes at least one of a second environmental magnetic field change, a second timestamp data, and a second Bluetooth distance range. Then, a second security key is calculated based on the first hash value of the first electronic device, the second hash value of the second electronic device, the second information, and the second data feature information corresponding to the shake operation. Since the first security key generated by the first electronic device based on the hash value of the electronic device, the environmental magnetic field change, the timestamp data, the Bluetooth distance range information, and the data feature information corresponding to the shake operation is the same as the second security key generated by the second electronic device, the second security key is the same. Therefore, when the first ciphertext sent by the first electronic device is received, the second ciphertext can be decrypted based on the second security key, and the decrypted second information can be obtained. This ensures that multiple electronic devices generate their own security keys without wireless transmission, preventing the keys from being leaked during transmission and thus ensuring the security of information interaction between electronic devices.

[0102] In some embodiments, step 402 above, calculating the second security key based on the first hash value of the first electronic device, the second hash value of the second electronic device, the second information, and the second data feature information corresponding to the shake operation, includes:

[0103] Step 4021: Receive the first hash value sent by the first electronic device;

[0104] Here, the user identifier of the first electronic device A can be represented as UIDA. The first hash value can be represented as: HUIDA = Hash(UIDA).

[0105] Step 4022: Perform a hash calculation on the user identifier of the second electronic device to obtain the second hash value;

[0106] Here, the user identifier of the second electronic device B can be represented as UIDB. A hash calculation is performed on the user identifier of the second electronic device to obtain a second hash value, which can be represented as HUIDB = Hash(UIDB).

[0107] Step 4023: Perform a hash calculation on the second information to obtain a fourth hash value;

[0108] In the second information, the change in the second environmental magnetic field is represented by Mb, the first timestamp data is represented by Tb, and the first Bluetooth distance range information is represented by Rb. Here, the second information is hashed to obtain the fourth hash value, which can be represented as HMTRb = Hash(Mb + Tb + Rb).

[0109] Step 4024: Determine the second locking key based on the second data feature information;

[0110] As an optional implementation, step 4024 may specifically include:

[0111] The second data feature information is quantized to obtain the second locking key.

[0112] In some embodiments, this step, which quantizes the second data feature information to obtain a second locking key, includes:

[0113] Based on the second data feature information, a second locking key is determined using a preset quantization rule; wherein the preset quantization rule is:

[0114] If the data is greater than or equal to the positive quantization threshold, then the key corresponding to the data is 1;

[0115] If the data is less than or equal to the negative quantization threshold, the key corresponding to the data is -1;

[0116] If the data falls between the positive quantization threshold and the negative quantization threshold, the corresponding key for the data is 0.

[0117] Analysis from the first electronic device shows that the second locking key KB is the same as the first locking key KA.

[0118] Step 4025: Obtain the second security key based on the first hash value, the second hash value, the fourth hash value, and the second locking key.

[0119] This step may specifically include: performing a hash calculation on the second locking key to obtain a sixth hash value; and obtaining a second security key based on the first hash value, the second hash value, the fourth hash value, and the sixth hash value.

[0120] Here, the sixth hash value can be represented as HKB = Hash(KB).

[0121] Specifically, the first hash value and the second hash value are XORed together, and then concatenated with the fourth and sixth hash values ​​to obtain the second security key. That is, the first security key HKeyB = HUIDA. A ⊕HUIDB+HMTRb+HKB.

[0122] As an optional implementation, the method of this application also includes:

[0123] Send the second hash value to the first electronic device.

[0124] Here, a second hash value is sent to the first electronic device for the purpose of generating a first security key on the first electronic device side.

[0125] In some embodiments, the method of this application further includes:

[0126] Periodically retrieve timestamp data;

[0127] The second security key is updated based on the timestamp data.

[0128] In this embodiment, in order to further enhance the security and randomness of the key, timestamp data is acquired periodically (i.e., periodically). The timestamp data is constantly changing, and the latest timestamp data is acquired periodically. The second information is updated using the timestamp data. Then, the updated second security key is obtained based on the first hash value of the first electronic device, the second hash value of the second electronic device, the updated second information, and the second data feature information corresponding to the shake operation.

[0129] Similarly, the first electronic device also periodically acquires timestamp data and updates the first security key based on the timestamp data. The update cycles for the timestamp data on both the first and second electronic devices are the same, and the updated second security key is identical to the updated first security key.

[0130] In some embodiments, the method of this application further includes:

[0131] Based on the second security key, the second information is symmetrically encrypted to obtain the second ciphertext;

[0132] Send the second ciphertext.

[0133] Since the first security key is the same as the second security key, the first electronic device can decrypt the second ciphertext after receiving the second ciphertext based on the first security key, and successfully decrypt the second ciphertext to obtain the decrypted second information.

[0134] See Figure 5 The following example illustrates the specific implementation process of the information sharing method of this application from the perspective of interaction between smart terminals (i.e., electronic devices).

[0135] exist Figure 5 The example includes the dynamic key update process of the smart terminal and the information security interaction process of the smart terminal.

[0136] The specific process for dynamically updating the key on a smart terminal is as follows:

[0137] Multiple users in the same environment simultaneously shake their respective smart terminals. The multiple smart terminal systems recognize the shake event and then execute step 501.

[0138] Step 501: Smart terminal A uses its own UIDA to generate HUIDA, i.e., HUIDA = Hash(UIDA). Similarly, smart terminal B uses its own UIDB to generate HUIDB, i.e., HUIDB = Hash(UIDB). Smart terminal C uses its own UIDC to generate HUIDC, i.e., HUIDC = Hash(UIDC).

[0139] Step 502: Smart terminal C sends HUIDC to the master device smart terminal A, and at the same time, smart terminal B sends HUIDB to the master device smart terminal A.

[0140] Step 503: After the master device smart terminal A has received all the HUIDx from all the smart terminals, it then sends HUIDx to all the slave device smart terminals x.

[0141] That is, smart terminal A sends UIDA and UIDC to smart terminal B, and smart terminal A sends UIDA and UIDB to smart terminal C.

[0142] Step 504: Smart terminal A acquires the environmental magnetic field change information Ma, the timestamp data of more than 100 digits Ta, and the Bluetooth distance range information Ra, and generates HMTRa, i.e., HMTRa = Hash(Ma + Ta + Ra); similarly, smart terminals B and C are similar: HMTRb = Hash(Mb + Tb + Rb); HMTRc = Hash(Mc + Tc + Rc).

[0143] Step 505: Smart terminal A extracts the data feature information corresponding to the shake operation, quantifies the data feature information, and generates the locking key KA; similarly, smart terminals B and C do the same.

[0144] Step 506: Generate HKA, i.e., HKA = Hash(KA); similarly, smart terminals B and C generate HKB = Hash(KB) and HKC = Hash(KC).

[0145] Step 507: Each smart terminal generates its own security key, namely, the security key HKeyA of smart terminal A is generated, HKeyA = HUIDA⊕HUIDB⊕HUIDC+HMTRb+HKA; similarly, smart terminals B and C generate security keys HKeyB = HUIDA⊕HUIDB⊕HUIDC+HMTRb+HKB and HKeyC = HUIDA⊕HUIDB⊕HUIDC+HMTRc+HKC, respectively.

[0146] The information security interaction process of the smart terminal is as follows:

[0147] Step 508: The information that smart terminal A needs to transmit is represented by Msga. The information Msga that needs to be transmitted is symmetrically encrypted using the dynamically generated HKeyA to obtain EMsga, that is, EMsga = AES-enc(HkeyA, Msga). Then, the encrypted information EMsga is sent to smart terminal B and smart terminal C.

[0148] Step 509: After receiving the encrypted information EMsga from smart terminal A, smart terminal B decrypts it using its own key HKeyB, i.e., Msga = AES - dec(HKeyB, EMsga), to obtain the plaintext information Msga from smart terminal A. Similarly, after receiving the encrypted information EMsga from smart terminal A, smart terminal C decrypts it using its own key HKeyC, i.e., Msga = AES - dec(HKeyC, EMsga), to obtain the plaintext information Msga from smart terminal A.

[0149] Step 510: Similarly, the information that smart terminal B needs to transmit is represented by Msgb. The information Msgb is symmetrically encrypted using its own key HKeyB to obtain EMsgb, i.e., EMsgb = AES - enc(HkeyB, Msgb). Then, the encrypted information EMsgb is sent to smart terminal A. Similarly, the information that smart terminal C needs to transmit is represented by Msgc. The information Msgc is symmetrically encrypted using its own key HKeyC to obtain EMsgc, i.e., EMsgc = AES - enc(HkeyC, Msgc). Then, the encrypted information EMsgc is sent to smart terminal A.

[0150] Step 511: After receiving the encrypted information EMsgb from smart terminal B, smart terminal A decrypts it using its own key HKeyA, i.e., Msgb = AES - dec(HKeyA, EMsgb), to obtain the plaintext information Msgb from smart terminal B. Similarly, smart terminal C does the same.

[0151] The keys for smart terminals are dynamically generated based on sensor data, changes in the ambient magnetic field, timestamp data, and Bluetooth range information. Therefore, the keys are generated in real-time, and the user is unaware of the generation process. Furthermore, the keys are never transmitted wirelessly, preventing leakage during transmission. These two unique methods enhance the security of information exchange between smart terminals.
