[Brief description of the drawings]

[0009] [Figure 1] FIG. 1 is a system block diagram of a management system that embodies a blockchain-based laboratory management method according to the present invention (Example 1). DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] User By managing and authenticating the right to use laboratory equipment, User However, when using some important equipment, authorization authentication is required, which can prevent unauthorized use of the equipment by inexperienced or insufficient personnel and further enhance safety. EXAMPLES

[0011] Step 1: Perform basic data input to input the compliance ID, including the object ID and the access data of the object; the object ID is the ID information of the laboratory personnel who are allowed to enter and operate the relevant equipment; the access data of the object includes the object key and the object ID. The object key is the password set for the corresponding object ID. Here, the password is User is the fingerprint. User When entering a password, you must enter the fingerprints of all five fingers of the specified hand. To synchronize, you must set an initial finger, which can be any finger on the specified hand; Object authority is expressed concretely as a number, and a correspondence table between numbers and authority is constructed in advance, where the larger the number, the greater the authority, and each number indicates that the experimental equipment below that number can be operated; In the lab, blockchain User The compliance IDs of each experiment are synchronized. device The lower bound of the object ID value required for the operation is synchronized.

[0012] Step 2: Synchronize on-chain compliance IDs and share compliance IDs to get on-chain data;

[0013] Step 3: Then, User When a person enters the lab, they are authenticated in the following way: S1: User Before entering the lab, you must first enter the object ID data. ID data is automatically assigned as identification data consisting of numbers when it is first entered by the administrator; S2: After inputting the ID data, generate a feature value through a random algorithm, and the feature value is a number between 1 and 5, including 1 and 5; the feature value generation method is as follows: S201: User entered ID data Time Get the date and time MinutesGet the time in the format, get 8 numbers so that the time point is before or after, and then get the time number column We obtain Ti,i=1,…,8; specifically, at this point, it is 14:43 on November 23, 2020, and Time If it is November 23rd at 14:43, the corresponding time digit string Ti,i=1,…,8 corresponds to 11231443 in order; S202: After that, time digit string Get the number of 5 or more in Ti, mark that number as a feature value, and automatically add 1 when the feature value becomes 0; here, Time There are restrictions on the acquisition method, time digit string Since none of the three numbers in can have a value greater than 5, we make the feature value strictly 5 or less, and avoid special cases by adding 1 to the 0. S203: Obtain the feature value. S3: Then, select a verification finger based on the feature value, and the verification fingers are selected in order from the thumb to the little finger, counting from the initial finger to the finger corresponding to the feature value, and marking it as the verification finger; S4: User At this point, the user needs to press the corresponding characteristic value of the finger on the laboratory access device to verify the corresponding verification finger; the user's ID is verified after passing through; User may be permitted to enter;

[0014] Step 4: User After entering, User Management of experimental equipment is carried out based on object ID and object authority, and all important experimental equipment in the laboratory is set up with startup verification modules, and important experimental equipment is pre-configured for administrators; certain equipment is expensive or requires strict operating qualifications; The startup authentication module is User This authentication module is used to verify the object authority of the chain, and is synchronized with the data on the chain. device The management methods are as follows: St1: User When you need to start up important lab equipment, you can start up the authentication module. User Automatically obtain a fingerprint of any specified hand, and then automatically obtain an object ID corresponding to the fingerprint, and then obtain the object ID; St2: Then, read the use authority of the experimental equipment, and the use authority is the lowest authority value corresponding to the use of the experimental equipment; St3: Compare the object permissions of the object ID with the usage permissions. If the object ID is equal to or greater than the usage permissions, User The experiment device otherwise, this experiment device will automatically power off. EXAMPLES

[0015] The second embodiment of the present invention is implemented based on the first embodiment, and differs from the first embodiment in the specific method of generating the representative value. In this embodiment, however, a different method of generating the representative value using a random algorithm is provided. Specifically: handle User Input ID data Time Get the date and time Minutes format and time point Get the 8 numbers from the front to the back of the time digit string Get Ti,i=1,...,8; Then, the sum with Ti is automatically taken and it is marked as H;H is divided by 5 and the remainder is taken to determine the remainder, and if it is 0, it is automatically added with 1 and made the feature value;If the remainder is not zero, the remainder is automatically marked as the feature value. EXAMPLES

[0016] As the third embodiment of the present invention, the present embodiment is different from the first embodiment in that step S4 of the first embodiment is as follows: User The user presses the finger corresponding to the feature value on the access control device in the laboratory, and the corresponding authentication finger is authenticated. Only after passing through can the user's ID be authenticated. User is allowed entry; in this step, User If you fail to verify the correct ID two times in a row, UserThe access privileges for the corresponding object ID are suspended, User must contact the administrator to cancel their access before entering. Of course, there could be many random algorithms, and we will only give two examples here.
