The project information sharing system provided by the invention can also have the technical characteristics that when the verification is not passed, the information without the right to access is fed back to the information access request.
The project information sharing system provided by the invention can also have the technical characteristics that the account information uniquely corresponds to the identity of a technician, and the information access record at least comprises the account information, the access time and the information abstract of the requested project encryption information.
The project information sharing system provided by the invention can also have the technical characteristics that the information abstract is an information access request.
The project information sharing system provided by the invention can also have the technical characteristics that the project information at least comprises technical data and experimental data shared by enterprise institutions aiming at the project.
Action and Effect of the invention
According to the project information sharing system, since the project encryption information is stored in the off-link project information database, and when a technician needs to access the project information, the project encryption information is verified through the account information, then the corresponding project encryption information is acquired to the enterprise terminal according to the information access request, and finally the decryption access is performed locally, the project information in the database can be prevented from being illegally acquired by a third party, the project information sharing among enterprise institutions can be ensured, and the cooperation of public security across departments is facilitated. In addition, as the corresponding information access record is generated and stored on the block chain when the block chain receives the information access request, the information access of each time can be guaranteed to be not falsifiable and have definite record, thereby being convenient for enterprise organizations to trace the information access and restricting illegal behaviors.

Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the project information sharing system of the invention is specifically described below with reference to the embodiment and the attached drawings.
< example >
Fig. 1 is a block diagram of a project information sharing system in the embodiment of the present invention.
As shown in fig. 1, a project information sharing system 10 includes a plurality of enterprise terminals 11 and a project information database 12.
The plurality of enterprise terminals 11 are held by a plurality of enterprise organizations, respectively, and each enterprise terminal 11 forms a block chain for managing and sharing information between the enterprise organizations as a block chain node.
In this embodiment, the enterprise terminal may be a computing device held by a technician such as a computer or a smart phone.
The project information database 12 stores a large amount of project encryption information in a daisy chain manner, and the project encryption information is obtained by encrypting the project information in advance according to a key and is stored.
In this embodiment, the project information is technical data, experimental data, and the like that are generated by an enterprise organization when a project is advanced and that can be shared with other cooperating enterprises, and the technical data are classified and numbered according to project categories, that is, each project information corresponds to a project number. When encryption is performed, information such as technical data and experimental data other than basic information such as an item number is encrypted.
Fig. 2 is a block diagram of an enterprise terminal in an embodiment of the present invention.
As shown in fig. 2, the enterprise terminal 11 has a user login module 111 and a project information acquisition module 112.
The user login module 111 is used for allowing a technician to input own account information to log in and authenticate the user.
The project information obtaining module 112 is configured to, when a technician inputs an information access request through the enterprise terminal 11 and the user login module 111 verifies that the account information passes, upload the information access request to the block chain in correspondence with the account information.
And then, the blockchain acquires corresponding project encryption information from the project information database according to the information access request, and generates a corresponding information access record based on the account information and the current time to store the corresponding information access record on the blockchain.
Specifically, in this embodiment, the information access request may be a search request or a data acquisition request, and the blockchain searches data such as an unencrypted item number in the item database according to the request to further acquire corresponding item encryption information.
Meanwhile, account information, access time and an information abstract are recorded in the information access record generated by the blockchain, so that a technician can determine the content of each access through the information access record. In this embodiment, the information digest is an information access request, and it is possible to determine which item encryption information is specifically acquired through the information access request.
The item information acquisition module 112 receives the item encryption information and decrypts the item information based on the key to obtain item information, which is further displayed by the enterprise terminal 11 for a technician to view.
Fig. 3 is a flowchart of the project information sharing system in the embodiment of the present invention.
As shown in fig. 3, once the technician enters account information via the enterprise terminal 11 for logging in, the following steps begin:
in step S1, the user login module 111 verifies the account information, and proceeds to step S2 when the verification is passed, and proceeds to step S5 when the verification is not passed
Step S2, the project information obtaining module 112 obtains the information access request input by the technician, and correspondingly uploads the information access request and the account information to the blockchain, and then the process goes to step S3;
step S3, the blockchain acquires corresponding project encryption information from the project information database according to the information access request, generates corresponding information access records based on the account information and the current time and stores the corresponding information access records on the blockchain, and then the step S4 is executed;
step S4, the item information obtaining module 112 receives the item encryption information, obtains item information based on key decryption, further displays the item information to the technician for viewing by the enterprise terminal 11, and then enters an end state;
in step S5, the information access request is fed back with the unauthorized access information, and the terminal state is entered.
Examples effects and effects
According to the project information sharing system provided by the embodiment, since the project encryption information is stored in the off-link project information database, and when a technician needs to access the project information, the project encryption information is verified through the account information, then the corresponding project encryption information is acquired to the enterprise terminal according to the information access request, and finally the decryption access is performed locally, the project information in the database can be prevented from being illegally acquired by a third party, the project information sharing among enterprise institutions can be ensured, and the cross-enterprise cooperation is facilitated. In addition, as the corresponding information access record is generated and stored on the block chain when the block chain receives the information access request, the information access of each time is guaranteed to be not falsifiable and has definite record, thereby being convenient for enterprise organizations to trace the information access and restricting the improper information acquisition behavior.
The above-described embodiments are merely illustrative of specific embodiments of the present invention, and the present invention is not limited to the description of the above-described embodiments.
