The invention relates to an electronic device, comprising an interface module, an encrypting-decrypting module, a storing module, an encoding-decoding module and an accessing module. The storing module is used for storing pre-set data. The encrypting-decrypting module is respectively connected with the interface module, the storing module and the encoding-decoding module. The encrypting-decryptingmodule is used for encrypting the received user data from the interface module by using the pre-set data and transferring the encrypted data to the encoding-decoding module for encoding and then theencoded data are stored into a storing medium by the storing module. The encrypting-decrypting module is also used for decrypting the received user data from the encoding-decoding module by using thepre-set data and transferring the decrypted data to the interface module to be output. Taking the pre-set data in the electronic device as an encrypted code can effectively avoid the illegal reading of the user data because other electronic devices cannot obtain the corresponding encrypted code and then cannot read the encrypted user data even though the storing medium is lost. Moreover, the invention also provides a data encrypting method and a data decrypting method.

The invention provides a data authentication system, which comprises a management server, at least one mirror image server and an authentication server, wherein the management server is used for receiving a first communication connection request, and transmitting a first digital certificate and a second digital certificate in the first communication connection request to the authentication server; the at least one mirror image server is used for receiving a second communication connection request, and transmitting the second digital certificate and the first digital certificate in the second communication connection request to the authentication server; the authentication server is used for judging whether the management server and the at least one mirror image server pass authentication or not, and if the management server and the at least one mirror image server pass the authentication, a communication connection is allowed to be established between the management server and the at least one mirror image server. The invention also provides a data authentication method. According to the technical scheme provided by the invention, the safety of patient information in the management server and the at least one mirror image server can be ensured, and therefore, the patient information in the management server and the at least one mirror image server is prevented from being illegally read, and illegal information is prevented from being written in the management server or the at least one mirror image server.

The invention provides a device used for preventing an unauthorized user from starting software. The device comprises a data interface, a storage and a main control chip. The data interface is used for transmitting obtained MAC addresses of a computer and input user passwords. The storage is used for storing system files, storing the MAC address and an account name which are obtained when the device is connected with the computer at the first time and storing the user password input at the first time. The main control chip is used for conducting verification on the obtained current MAC address of the computer and the original MAC address obtained at the first time and conducting verification on the current input user password and the original user password input at the first time and executes related operations according to verification results. A method with the device adopted comprises the steps that if the obtained current MAC address of the computer is the same as the original computer MAC address obtained at the first time, a user password input window is popped up; if the current input user password is the same as the original user password input at the first time, software is started. According to the method and device for preventing the unauthorized user from starting the software, after it is determined that the current computer is not bonded with a USERKEY, the specific software cannot be started so as to guarantee the safety and the effectiveness of the software.

The application discloses a storage method, device and equipment for driving data. A specific embodiment of the storage method of the driving data includes: analyzing the importance of the received driving data to determine the storage level of the driving data; obtaining the corresponding key and encryption algorithm according to the storage level of the driving data; The driving data is encrypted using a key and an encryption algorithm; the encrypted driving data is stored in a storage area corresponding to the storage level of the driving data. This embodiment can improve the security of driving data by encrypting and storing data in different levels, effectively prevent important driving data from being illegally read or maliciously tampered with, and can improve the storage efficiency of driving data at the same time.
