Close algorithm routine, execute to already present other be of little use user carry out delete operation.In the deletion behaviour for executing the user that is of little use
Before work, whether the user that first checks for being of little use if having if first deletes the be of little use user pair with corresponding Encryption Algorithm
Then the Encryption Algorithm answered deletes the user that is of little use；If not having, the user that is of little use directly is deleted, this instruction is terminated.
User management instruction is changed if user right to be instructed, then it represents that executes user right modification operation.Verification is worked as
Whether the permission of preceding user passes through, and is grasped if, according to the permission of instruction modification user, otherwise directly terminating this instruction if
Make.
Preferably, when executing subscriber management function, verification active user's permission is all added after receiving instruction
Function, safely and effectively managed with the user ensured in image information collecting device.
After encryption unit receives the instruction in enabling signal, judge to include that management of encryption algorithms refers in enabling signal
It enables, executes management of encryption algorithms block process, as shown in Fig. 3.
The user instruction is added if Encryption Algorithm and is instructed, then it represents that has the correspondence Encryption Algorithm of new user to store into adding
In the management of encryption algorithms module of close unit（Or there is the Encryption Algorithm of the corresponding new version of user to store into encryption unit
In management of encryption algorithms module）, Encryption Algorithm addition operation is executed, finds in instruction and corresponds to new user to be added, and verify
Its permission adds the correspondence Encryption Algorithm of new user if being verified, and terminates this instruction operation；It is straight not if if verification
Binding beam.
The user instruction is deleted if Encryption Algorithm and is instructed, then it represents that it is corresponding that controller insufficient memory stores user
Cryptographic algorithm process executes the Encryption Algorithm delete operation to being of little use, and finds the corresponding user deleted in instruction, finds out the use
Whether family possesses this Encryption Algorithm, if directly terminating this instruction operation without if, if possessing this Encryption Algorithm, verifies the use
The permission at family does not terminate this instruction operation if verification if, if by deleting the algorithm, and terminate this instruction.
User management module and management of encryption algorithms module then realize the different Encryption Algorithm progress to multiple manufacturer users
Dynamic manages in real time, meets the demand for security of each businessman.

12. the method that image data is encrypted in image information collecting device according to claim 11, feature exist
In the step (31), it is equipped with the verification step of the authentication unit between the collecting unit and the encryption unit, tests
Card step includes the following steps：
Authentication unit receives image data from collecting unit, examines whether the image currently acquired meets picture size and picture matter
The shooting condition of amount notifies collecting unit to stop acquisition if having met, and the encrypting module is notified to obtain collecting unit
Otherwise the image data of acquisition continues to examine whether the image currently acquired meets shooting condition.
