[0048] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The embodiments will now be described in detail with reference to the accompanying drawings.

[0049] It should be noted that the acquisition, storage, use, and processing of data in the technical solution of this application all comply with the relevant provisions of national laws and regulations.

[0050] Specifically, in order to address the problems of the prior art, embodiments of this application provide a method, apparatus, device, storage medium, and program product for acquiring information. The method for acquiring information provided in the embodiments of this application will be described first below.

[0051] Figure 1 A flowchart illustrating an embodiment of an information acquisition method provided in this application is shown. The method includes the following steps:

[0052] S110, if a first information identifier is detected being sent from the first terminal device to the second terminal device, the first information identifier is intercepted.

[0053] In this embodiment, the first terminal device can be a backend server, the second terminal device can be a user terminal, and the interception device can perform data interception and other specific functions on the communication path between the first terminal device and the second terminal device.

[0054] Specifically, the user can select an account that the user wants to query on the second terminal device, and generate a first query request based on the account selected by the user, send the first query request to the first terminal device by the second terminal device, and the first terminal device obtains the information identifiers of all information corresponding to the account based on the first query request, and sends these information identifiers to the second terminal device. For example, the information identifier can be the UUID (Universally Unique Identifier, Universal Unique Identifier) or GUID (Globally Unique Identifier, Globally Unique Identifier) of the information

[0055] The interception device can set an interceptor on the communication path of the first terminal device and the second terminal device to intercept the information identifiers sent by the first terminal device to the second terminal device. After intercepting the information identifiers, these information identifiers will no longer be sent to the second terminal device.

[0056] S120, encrypting the first information identifier to obtain an encrypted string.

[0057] In this embodiment, the first information identifier is any one of the information identifiers sent by the first terminal device to the second terminal device and intercepted by the interception device. Taking the first information identifier as an example, the interception device can encrypt the first information identifier to convert the first information identifier into an encrypted string. For example, the first information identifier can be encrypted by using an encryption algorithm such as SM4 algorithm, DES (Data Encryption Standard) algorithm or RSA (Rivest-Shamir-Adleman) algorithm.

[0058] S130, associating the encrypted string and the first information identifier, and sending the associated encrypted string and the first information identifier to the second terminal device, so that the second terminal device queries the detailed information corresponding to the first information identifier from the first terminal device through the associated encrypted string and the first information identifier.

[0059] In this embodiment, since the first information identifier sent by the first terminal device to the second terminal device is intercepted by the interception device, the first information identifier will be obtained by the interception device and will not continue to be transmitted to the second terminal device. After the interception device intercepts the first information identifier, the first information identifier is encrypted to obtain an encrypted string, and the interception device can associate the encrypted string and the first information identifier, and send the associated encrypted string and the first information identifier to the second terminal device.

[0060] In this way, the second terminal device can receive the first information identifier sent by the intercepting device and the encryption string associated with the first information identifier. The second terminal device can display the received first information identifier on a display interface. The user can perform a first input on the first information identifier, and the first input means that the user wants to query detailed information corresponding to the first information identifier. Then, the second terminal device can send the first information identifier and the encryption string associated with the first information identifier to the second terminal device. In a case where the first information identifier and the encryption string pass consistency verification, the first terminal device will return detailed information corresponding to the first information identifier to the second terminal device.

[0061] In the embodiment of the application, after detecting that the first terminal device sends the first information identifier to the second terminal device, the first information identifier can be intercepted and encrypted to obtain an encryption string. Then, the encryption string and the first information identifier are associated and sent to the second terminal device. Then, the second terminal device can query detailed information corresponding to the first information identifier from the first terminal device by using the associated encryption string and the first information identifier. Compared with the related art in which information is queried only by using the first information identifier, the encryption string obtained by encrypting the first information identifier is also used as a condition for information query in the application. Since the encryption string is not easy to be guessed by an illegal user, data query by using the information identifier and the encryption string can effectively avoid the risk of data leakage.

[0062] As an optional embodiment, the encryption processing on the first information identifier to obtain the encryption string includes:

[0063] determining an intercepting time corresponding to the first information identifier, wherein the intercepting time is a time at which the intercepting device intercepts the first information identifier;

[0064] generating a time stamp corresponding to the intercepting time;

[0065] encrypting the first information identifier and the time stamp to obtain the encryption string.

[0066] In the embodiment, in the process in which the intercepting device intercepts the first information identifier, the time at which the intercepting device intercepts the first information identifier is determined as the intercepting time. Then, a time stamp corresponding to the intercepting time is generated, and the time stamp and the first information identifier are encrypted to obtain an encryption string. The encryption string records information of the first information identifier and information of the intercepting time, and therefore the encryption string is unique.

[0067] For example, the timestamp and the first information identifier can be combined and then encrypted to obtain an encrypted string; or the timestamp and the first information identifier can be encrypted respectively to obtain two sub-strings, and the two encrypted sub-strings can be combined to obtain the encrypted string.

[0068] In this way, the interception moment can be encrypted together with the first information identifier in the form of a timestamp, so that the encrypted string is unique and cannot be guessed, thereby improving the security of the encrypted string.

[0069] As an optional embodiment, after the encrypted string and the first information identifier are associated and the associated encrypted string and the first information identifier are sent to the second terminal device, the method further comprises:

[0070] intercepting the first information identifier and the encrypted string with the association relationship when it is detected that the second terminal device sends the first information identifier and the encrypted string with the association relationship to the first terminal device;

[0071] decrypting the encrypted string to obtain a second information identifier;

[0072] when the first information identifier and the second information identifier match, sending the first information identifier to the first terminal device, so that the first terminal device sends detailed information corresponding to the first information identifier to the second terminal device.

[0073] In this embodiment, the second terminal device is a user terminal, and the first terminal device can be a background server. When the second terminal device sends the first information identifier and the encrypted string with the association relationship to the first terminal device, it means that the second terminal device wants to query detailed information corresponding to the first information identifier from the first terminal device.

[0074] The interception device is arranged on the transmission path between the first terminal device and the second terminal device, so the interception device can not only set an interceptor to intercept the first information identifier sent by the first terminal device to the second terminal device, but also set another interceptor to intercept the first information identifier and the encrypted string with the association relationship sent by the second terminal device to the first terminal device.

[0075] After intercepting the first information identifier and the encrypted string having the correlation relationship, the intercepting device can perform decryption processing on the encrypted string to obtain the second information identifier in the encrypted string. If the first information identifier and the second information identifier are consistent, it is considered that the first information identifier and the encrypted string having the correlation relationship come from the user terminal, and the first terminal device can provide the detailed information corresponding to the first information identifier to the second terminal device. Therefore, the intercepting device can send the first information identifier to the first terminal device. After the first terminal device receives the first information identifier, the first terminal device queries the detailed information corresponding to the first information identifier in the database and feeds back the detailed information corresponding to the first information identifier to the second terminal device.

[0076] In the embodiment, the intercepting device can intercept the information identifier and the encrypted string having the correlation relationship, and verify the intercepted information identifier and the encrypted string. Only when the information identifier passes the verification, the background server is allowed to transmit the corresponding detailed information to the user terminal. In this way, it can be ensured that the information query comes from a legal channel, and the security of the information is ensured.

[0077] As an optional embodiment, the decryption processing on the encrypted string to obtain the second information identifier includes:

[0078] The decryption processing on the encrypted string to obtain the second information identifier and a time stamp;

[0079] The sending of the first information identifier to the first terminal device in the case where the first information identifier and the second information identifier match, so that the first terminal device sends the detailed information corresponding to the first information identifier to the second terminal device includes:

[0080] The sending of the first information identifier to the first terminal device in the case where the first information identifier and the second information identifier match, and the interval time length between the interception time corresponding to the time stamp and the current time is less than a time length threshold, so that the first terminal device sends the detailed information corresponding to the first information identifier to the second terminal device.

[0081] In the embodiment, after the intercepting device intercepts the first information identifier and the encrypted string having the correlation relationship, the intercepting device can perform decryption processing on the encrypted string to obtain not only the second information identifier in the encrypted string but also the time stamp corresponding to the interception time of the first information identifier.

[0082] So after obtaining the second information identifier and the time stamp, if the first information identifier matches the second information identifier and the interval between the interception time corresponding to the time stamp and the current time is less than the time threshold, it not only indicates that the information identifier of the query information comes from a legal channel, but also indicates that the process from obtaining the information identifier to querying the corresponding detailed information using the information identifier is within a short time interval and is a coherent operation. Therefore, the interception device can send the first information identifier to the first terminal device. After the first terminal device receives the first information identifier, the first terminal device queries the detailed information corresponding to the first information identifier in the database and feeds back the detailed information corresponding to the first information identifier to the second terminal device.

[0083] If the first information identifier does not match the second information identifier or the interval between the interception time corresponding to the time stamp and the current time is greater than or equal to the time threshold, the interception device can consider that the first information identifier comes from an illegal channel, and therefore does not send the first information identifier to the first terminal device, thereby blocking the information query. In this way, the interception device can intercept query requests from illegal channels, thereby improving the security of the information.

[0084] Figure 2 A flowchart of an information acquisition method provided by an embodiment of the present application is shown. The method is applied to a second terminal device and includes the following steps:

[0085] S210, in response to a first input of a user to the displayed first information identifier;

[0086] S220, sending the first information identifier and an encrypted string having an association relationship with the first information identifier to a first terminal device;

[0087] S230, in a case where the first information identifier matches a second information identifier in the encrypted string, receiving detailed information corresponding to the first information identifier sent by the first terminal device.

[0088] In this embodiment, the second terminal device can obtain at least one information identifier of information that the user wants to query from the first terminal device, and then display the at least one information identifier on a display interface. The user can select a first information identifier in the at least one information identifier for a first input. The second terminal device obtains an encrypted string having an association relationship with the first information identifier in response to the first input, and then sends the first information identifier and the encrypted string having the association relationship with the first information identifier to the second terminal device. Only when the first information identifier matches the second information identifier in the encrypted string, the first terminal device sends the detailed information corresponding to the first information identifier to the second terminal device.

[0089] After the second terminal device receives the first information identifier, the detailed information corresponding to the first information identifier can be displayed for the user to view.

[0090] In this way, the background server is allowed to transmit the detailed information corresponding to the first information identifier to the user terminal only when the information identifier is verified, which can ensure that the information query comes from a legal channel and guarantee the security of the information.

[0091] As an optional embodiment, the receiving, in a case where the first information identifier and the second information identifier in the encrypted string match, of the detailed information corresponding to the first information identifier sent by the first terminal device comprises:

[0092] The receiving, in a case where the first information identifier and the second information identifier in the encrypted string match and the interval between the time stamp and the current time is less than the time length threshold, of the detailed information corresponding to the first information identifier sent by the first terminal device.

[0093] As an optional embodiment, before the responding to the first input of the user on the displayed first information identifier, the method further comprises:

[0094] In response to a second input of the user, generating an information query request;

[0095] Sending the information query request to the first terminal device;
