The convenient and safe operation of reading specific data for specific clients is added in the implementation mode, and the method specifically comprises the following steps: after the cloth cover 44 is installed in place, the digital code at the position of the first handle 6 and the distance of the digital code which is known in advance are stored on the cloth cover, and the rotating speed of the third motor 41 and the distance of the digital code are preset in the controller of the electronic touch writing board 54, a cyclic digital code of 0-9 is sequentially arranged along one edge of the cloth cover 44 along the length direction thereof at equal intervals, that is, 012345678901234567890123456789 … … sequence, so that the digital code at the position of the first handle 6 can be uniquely determined only in the case that the curtain is rotated uniformly and forwards, according to the distance of the digital code and the digital code at the starting time and the rotating speed of the motor or the rotating speed of the curtain, in the case that the rotating time length is determined, and in addition, a plurality of initial passwords corresponding to each bidding document, one of which is 0324, are stored in the electronic touch writing board and are known in advance only for a specific client of the bidding document, a timer is built in the electronic touch writing board 54, the electronic touch writing board 54 starts to rotate from the motor 41 to start timing synchronously, when a certain client needs to call up a bidding encrypted file, only a single finger needs to touch the electronic touch writing board 54, at this time, the writing board 54 sends a trigger signal to control the third motor 41 to stop rotating and the timer to stop counting, the current counting is N, according to the counting duration, the rotating speed and the distance of the digital codes of the third motor 41, and the digital codes on the lower cloth 44 of the first handle 6 when the cloth 44 is initially started, the digital codes under the electronic touch writing board 54 when the electronic touch writing board 54 is triggered by the current finger are obtained, for example, 3, as a reference key, the current code of the bidding file with the initial code of 0324 should be: 0962, i.e. each number multiplied by the key is left as a one-digit number, and a specific client who is pre-aware of the rule only needs to look at the number code under the first handle 6 with eyes and perform a simple calculation of the rule, and then enter it in the code box popped up by the electronic touch tablet 54: 0962 the controller of the electronic touch tablet performs inverse operations according to the current number code at the position of the first handle 6, i.e. the reference key position, each number is divided by 3 to obtain one digit (which is less than 3 plus 10 to obtain dividend), i.e. the touch pad calls the file with initial code 0324 to idle on the display or provide copying or printing function. The method can ensure that even if other people see the password, the password input at different times can be invalid, thereby achieving the effect of preventing stealing the password.
Therefore, the design can intelligently store and verify the encrypted information of the specific file and some random factors, and can reliably perform encryption retrieval.
The screen may also be printed with other promotional information in addition to the digital code.
