The invention discloses a method for displaying encrypted information. The method includes the following steps of obtaining verification information input by a user, wherein the verification information is used for checking the encrypted information of a current application program; displaying the encrypted information on an interface of the current application program if the verification information input by the user is consistent with preset verification information. The invention further discloses a terminal for displaying the encrypted information. The method and terminal need the verification step that information needs to be verified before the encrypted information is displayed in the interface of the current application program, effectively prevent others from checking the encrypted information in the terminal, are higher in safety, and avoid the phenomenon that personal user information contained in the encrypted information is leaked.

The embodiment of the invention discloses a data transmission method, comprising: when a vehicle terminal is required to send data to be sent to a server in connection with the vehicle terminal, the vehicle terminal generating a private key according to a preset rule; the vehicle terminal encrypting the data to be sent according to the private key to obtain a signature; and the vehicle terminal deleting the private key, and sending the signature and the data to be sent to the server in connection with the vehicle terminal. The embodiment of the invention also discloses a device and a system. According to the invention, the data transmission security of the vehicle terminal can be improved.

The embodiment of the invention discloses an encryption method, device and equipment based on features of information and a storage medium, and the method comprises the steps: obtaining a target function for describing information, and the feature information of to-be-processed target information; dividing the target information according to the feature information of the target information to obtain at least two pieces of sub-information; obtaining coordinate information corresponding to each piece of sub-information in the at least two pieces of sub-information according to the target function; encrypting the coordinate information of each piece of sub-information in the at least two pieces of sub-information to obtain a ciphertext of the coordinate information corresponding to each piece of sub-information; and determining the ciphertext of the coordinate information corresponding to each piece of sub-information as the ciphertext of the target information, and storing the ciphertext of the target information in a blockchain network. By adopting the method, the security of the target information can be improved, the method is suitable for the field of smart medical treatment, and the construction of smart cities can be further promoted.

The invention discloses a secret divulging prevention method, a terminal and a computer readable storage medium. According to the method, a to-be-detected file is picked up through a multimedia pickupdevice in a terminal; whether a preset confidential object exists in the to-be-detected file or not is judged; if yes, the to-be-detected file is processed according to a preset anti-divulging processing mode. The defect that the user experience satisfaction degree is low due to the fact that confidential files are prone to flow out in the prior art is overcome. The invention further discloses the terminal and the computer readable storage medium, by implementing the scheme, when the file with the secret object is detected, the file can be processed, so that the file is prevented from being leaked, and the user experience is improved.

The embodiment of the invention discloses an encryption method and device based on a shared root key, equipment and a medium, and relates to a block chain technology. The method comprises the steps: obtaining a target function used for describing information and a root key corresponding to target information to be processed, wherein the target information comprises at least two pieces of sub-information; generating a key of each piece of sub-information in the at least two pieces of sub-information according to the root key; obtaining coordinate information corresponding to each piece of sub-information in the at least two pieces of sub-information according to the target function; encrypting the coordinate information corresponding to each piece of sub-information in the at least two pieces of sub-information by adopting the key of each piece of sub-information to obtain a ciphertext of the coordinate information corresponding to each piece of sub-information; and determining the ciphertext of the coordinate information corresponding to each piece of sub-information as the ciphertext of the target information, and storing the ciphertext of the target information in a block chain network. By adopting the method, the security of information can be improved, the method is suitable for the field of smart medical treatment, and the construction of smart cities can be further promoted.

The invention relates to a palmprint and face recognition method based on a cellular neural network hetero-associative memory model, and belongs to the technical field of intelligent recognition. Themethod comprises registration and identification. According to the method, the hetero-associative memory and the cellular neural network model are combined; palm print picture data and face picture data are converted into a series of parameters to be stored, identity information, namely the palm print picture data and the face picture data, is high in verification reliability, the picture storagemode is high in confidentiality and safety coefficient, and the identity information of people is effectively prevented from being leaked. The mode of converting the picture into the parameter throughthe model is adopted, and the method is simple, convenient, good in practicability, good in picture recognition effect and good in face picture data protection effect.

The invention relates to a method and device for distributing a document permission. The method includes the steps of obtaining a document with a to-be-distributed permission; calculating a document value of the document with the to-be-distributed permission; according to the document value of the document with the to-be-distributed permission and document values of documents with existing permissions, calculating a distance value between the document with the to-be-distributed permission and each document with the existing permission; in the distance values obtained through calculation, determining a minimum distance value; when the minimum distance value is smaller than a preset threshold, distributing the permission of the document with the existing permission corresponding to the minimum distance value to the document with the to-be-distributed permission. The device includes an obtaining module, a first calculation module, a second calculation module, a determination module and adistribution module. The method and the device can automatically distribute the document permission to the new document, and avoid the new document from the risk of being disclosed or illegally accessed due to permission lack.

The invention discloses a method and a system for realizing login through borrowing an account of others. The method comprises the following steps that according to an account borrowing request of a borrowing party, a first APP on a borrowing party mobile terminal sends a temporary password input by the borrowing party to an account borrowing management server; the first APP on the borrowing party mobile terminal receives a first account authentication cache file corresponding to the temporary password from the account borrowing management server and stores the first account authentication cache file at a specified position on the borrowing party mobile terminal, wherein the first account authentication cache file contains first account authentication cache information needed for a loaning party to login to a second APP; according to the first account authentication cache file stored at the specified position, the second APP on the borrowing party mobile terminal logins to a server of the second APP by making use of the first account authentication cache information contained in the first account authenticationcache file, namely, the loaning party can enable others to login at a specified application website through the account of the loaning party without providing the account and the password on the specified application website.
