[0026] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] Figure 1 It is a schematic diagram of an application scenario of the method for storing information in some embodiments of the present disclosure.

[0028] exist Figure 1In the application scenario, the electronic device 101 receives a storage information request 102, which includes the information to be shared 103. The electronic device 101 generates an information storage address 104 and a first description information 105 (which may be ["management", "information"]) according to the information to be shared 103, and the first description information 105 is used to describe the information content of the information to be shared 103. In response to generating the first description information 105, the electronic device 101 generates an information sharing constraint 106 corresponding to the first description information 105 (which may be ["student", "teacher", "greater than or equal to 5 (yuan)"]). Other users need to meet at least one of the information sharing constraint conditions 106 to obtain the information to be shared 103. Then, the information sharing constraint conditions 106, the first description information 105, and the information storage address 104 are stored in the blockchain. In response to receiving a confirmation signal 107 of successful storage sent by other terminal devices, a storage success message 108 (which may be "successful storage") is sent to the device storing the information to be shared 103.

[0029] It should be understood that Figure 1 The number of electronic devices 101 in the embodiment is only for illustration. Any number of electronic devices 101 may be provided according to implementation requirements.

[0030] Figure 2 It is a schematic diagram of an application scenario of the method for obtaining information in some embodiments of the present disclosure.

[0031] exist Figure 2 In the application scenario of , the electronic device 201 receives the information acquisition request 203, which includes the second description information 204 (which may be "management") and the user attribute information 206 (which may be ["student", "10 (yuan)"]), and the second description information 204 is used to describe the request content of the information acquisition request 203. The electronic device 201 queries the first description information 205 (which may be ["management", "information"]) corresponding to the second description information 204 on the block 202. In response to the query of the first description information 205 corresponding to the second description information 204, the electronic device 201 matches the information sharing constraint 207 (which may be ["student", "teacher", "greater than or equal to 5 (yuan)"]) corresponding to the first description information 205 with the user attribute information 206. The "student" in the user attribute information 206 is included in the information sharing constraint 207, and the "10 (yuan)" in the user attribute information 206 satisfies the condition of "greater than or equal to 5 (yuan)" in the information sharing constraint 207. It can be seen that the user attribute information 206 meets the restriction condition in the information sharing constraint condition 207. In response to receiving a signal of successful matching, the information storage address 208 corresponding to the first description information 205 is queried on the blockchain, and the shared information 212 is obtained according to the information storage address 208.

[0032] It should be understood that Figure 2 The number of electronic devices 201 in the embodiment is only for illustration. Any number of electronic devices 201 may be provided according to implementation requirements.

[0033] Continue to refer Figure 3 , shows a process 300 of some embodiments of the method for storing information according to the present disclosure. The method for storing information includes the following steps:

[0034] Step 301: receiving a storage information request, where the storage information request includes information to be shared.

[0035] In some embodiments, the execution subject of the method of storing information (eg Figure 1 The electronic device 101 shown may receive the request for storing information via a wired connection or a wireless connection. It should be noted that the wireless connection may include but is not limited to 3G / 4G / 5G connection, WiFi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (ultra wideband) connection, and other wireless connection methods currently known or to be developed in the future. As an example, the information to be shared may be information about text or information about images.

[0036] Step 302: Generate first description information and an information storage address according to the information to be shared, where the first description information is used to describe the information content of the information to be shared.

[0037] In some embodiments, the first description information and the information storage address are generated based on the information to be shared in the storage information request in step 301. As an example, the execution subject may store the information to be shared in the storage information request to a designated storage device A, and use the storage address returned by the storage device A as the information storage address. As an example, the first description information may be a summary of the content of the information to be shared (e.g., ["About information management"]).

[0038] In some optional implementations of some embodiments, generating the first description information according to the information to be shared includes: generating the first description information according to keywords in the information to be shared. As an example, the most frequently appearing words in the information to be shared can be used as keywords, and the keywords can be "management" and "information". The first description information can be keywords of the content to be obtained, such as ["management", "information"].

[0039] In some optional implementations of some embodiments, generating an information storage address according to the information to be shared includes: storing the information to be shared in a specified location, and obtaining the information storage address of the specified location. As an example, the specified location can be any specified server, and the information storage address is generated according to the storage location returned by the stored server.

[0040] Step 303: in response to generating the first description information, generate information sharing constraint conditions corresponding to the first description information.

[0041] In some embodiments, as an example, the information sharing constraint condition may be generated by the constraint condition pre-set by the execution subject, or the information sharing constraint condition may be generated by querying a table about the first description information and the information sharing constraint condition. As an example, the information sharing constraint condition may be the specified user identity information, the fee to be paid for obtaining the information, etc. As an example, the information sharing constraint condition may be ["student", "teacher", "greater than or equal to 5 (yuan)"].

[0042] In some optional implementations of some embodiments, before generating the information sharing constraint corresponding to the first description information, the method further includes: in response to receiving the storage information request, displaying a constraint selection interface, the constraint selection interface displays at least one shared user attribute and a shared reward input box, and the shared user attribute may include a user identity attribute. As an example, the shared user attribute displayed on the constraint selection interface is ["student", "teacher"].

[0043] In some optional implementations of some embodiments, generating the information sharing constraint corresponding to the first description information includes: in response to receiving at least one shared user attribute and shared remuneration of the corresponding constraint selection interface, encapsulating the at least one shared user attribute and shared remuneration into the information sharing constraint. As an example, the above-mentioned execution subject encapsulates the at least one shared user attribute and shared remuneration into the information sharing constraint ["student", "teacher", "greater than or equal to 5 (yuan)"] in response to receiving at least one shared user attribute ["student", "teacher", "greater than or equal to 5 (yuan)"] of the corresponding constraint selection interface.

[0044] Step 304: store the information sharing constraint, the first description information, and the information storage address in the blockchain.

[0045] In some embodiments, as an example, the information sharing constraints may include user identity information and the fee required to obtain the information (eg, ["student", "teacher", "greater than or equal to 5 (yuan)"]).

[0046] Step 305: In response to receiving a confirmation signal indicating successful storage, a storage success message is sent.

[0047] In some embodiments, as an example, the execution subject sends a storage success message "Stored successfully" in response to receiving a confirmation signal of successful storage.

[0048] Some embodiments of the present disclosure disclose a method for storing information, which realizes the secure storage of data and is conducive to data management. Specifically, the inventors found that the reason why information cannot be stored securely is that most cloud storage sharing systems adopt a centralized management mode, that is, information is uniformly managed with the help of a central server, which easily causes excessive server access, and the centralized management mode is not conducive to the secure storage of data. Based on this, the method for storing information in some embodiments of the present disclosure can store and manage data through blockchain, so that data is no longer centrally managed, which is conducive to the secure storage of data. In addition, the formulation of sharing constraints also reduces the high-frequency access pressure of the server, reduces the cost of data management, and is conducive to data management.

[0049] Further references Figure 4 , which shows a process 400 of another embodiment of a method for obtaining information. The process 400 of the method for obtaining information includes the following steps:

[0050] Step 401: Receive a request for obtaining information.

[0051] In some embodiments, the method for obtaining information is executed on an execution subject (eg, Figure 2 The electronic device 201 shown can receive the information acquisition request through a wired connection or a wireless connection, wherein the information acquisition request includes the second description information and the user attribute information, and the second description information is used to describe the request content of the information acquisition request. As an example, the second description information can be ["management"], and the user attribute information can be ["student"].

[0052] Step 402: query the blockchain for the first description information corresponding to the second description information.

[0053] In some embodiments, as an example, the first description information may be ["management", "information"], the second description information may be ["management"], and the first description information corresponding to the second description information is queried.

[0054] Step 403: In response to querying the first description information corresponding to the second description information, matching the information sharing constraint condition corresponding to the first description information with the user attribute information.

[0055] In some embodiments, user attribute information needs to satisfy at least one of the information sharing constraints in order to obtain information. As an example, the first description information may be ["management", "information"], and the second description information may be ["management"], in response to a query finding that the information content in the first description information includes the information content of the second description information. Then, the information sharing constraint corresponding to the first description information (such as ["student", "greater than or equal to 5 (yuan)"]) is matched with the user attribute information (such as ["student"]), and the information sharing constraint contains the user attribute information ["student"], so the match is successful.

[0056] In an optional implementation of some embodiments, the user attribute information includes local user attributes and user balance, the information sharing constraint includes at least one shared user attribute and a shared reward; and matching the information sharing constraint corresponding to the first description information with the user attribute information includes: matching the local user attribute with at least one shared user attribute; in response to the local user attribute successfully matching the at least one shared user attribute, matching the user balance with the shared reward. As an example, the local user attribute may be ["student"], and the user balance may be ["10 (yuan)"]. The at least one shared user attribute included in the information sharing constraint may be ["student", "teacher"], and the shared reward included in the information sharing constraint may be ["greater than or equal to 5 (yuan)"], so the information sharing constraint may be ["student", "teacher", "greater than or equal to 5 (yuan)"]. The local user attribute ["student"] is matched with at least one shared user attribute ["student", "teacher"]. In response to the successful matching of the local user attribute with at least one shared user attribute (at least one shared user attribute ["student", "teacher"] contains the local user attribute ["student"]), the user balance ["10 (yuan)"] is matched with the shared reward ["greater than or equal to 5 (yuan)"].

[0057] In some optional implementations of the embodiments, matching the user balance with the shared reward includes: settling the shared reward and the user balance. The execution subject may settle the user balance by subtracting the shared reward. For example, the user balance may be [“10 (yuan)”], the shared reward may be [“greater than or equal to 5 (yuan)”], and the final user balance is [“5 (yuan)”].

[0058] Step 404, in response to receiving a signal indicating successful matching, querying an information storage address corresponding to the first description information on the blockchain, and obtaining shared information according to the information storage address.

[0059] In some embodiments, the information storage address may be obtained by querying a table of information storage addresses corresponding to the first description information.

[0060] Some embodiments of the present disclosure disclose a method for obtaining information, which realizes the secure acquisition of data and reduces the number of visits to the server storing the data. Specifically, the inventors found that the reason why information cannot be stored securely and the server has too many visits is that most cloud storage sharing systems adopt a centralized management model, that is, information is managed uniformly with the help of a central server. Based on this, the method for obtaining information in some embodiments of the present disclosure can obtain data through blockchain, which is conducive to the secure acquisition of data. Moreover, the formulation of sharing constraints also reduces the high-frequency access pressure of the server, screens out some users who do not meet the sharing constraints, thereby reducing the access pressure on the server.
