The application relates to the field of video applications, and provides a video desensitization method and device, electronic equipment and a computer program product. The method comprises the following steps: acquiring video data, identifying a human hand region based on the video data, obtaining N gesture recognition results and M hand contact article recognition results, determining a sensitive region and a target sensitive level according to the N gesture recognition results and the M hand contact article recognition results, and performing desensitization processing on the video data according to the sensitive region and the target sensitive level. The video desensitization method provided in the embodiment of the application can solve the technical problem that a hand contact article or hand operation of a photographed person cannot be desensitized, personal information of the photographed person is easily leaked, and the personal information safety of the photographed person is improved.

This application provides an anti-tamper device and a communication device. The anti-tamper device is installed in the communication device and includes: a vulnerable unit, the first end of which is fixed inside the casing of the communication device. The vulnerable unit includes multiple lines, some of which are in a conductive state and others are in a disconnected state; a pull-up module, which is coupled to the first end of each line, and the coupling point between the pull-up module and each line is connected to the controller of the communication device. The pull-up module is powered by the communication device, and the second end of each line is grounded. When the communication device is disassembled, all the lines in the vulnerable unit are disconnected, and the controller receives an electrical signal indicating that the communication device has been disassembled. By using the random on / off states of multiple lines, the device is determined to have been disassembled. After the device is disassembled, all the lines are disconnected, making it impossible to determine the original state of the lines, thereby achieving the anti-tamper function.

This application discloses a data processing method, apparatus, device, storage medium, and program product, relating to the field of data processing technology. The method includes generating a privacy vector and a public key vector based on anonymity query rule data and public parameters, where the public parameters are jointly determined by the data queryer and the data provider; sending an anonymity request to the data provider, the anonymity request carrying the public key vector, the anonymity request being used by the data provider to generate a secret vector and a secret number, the secret vector being a vector in which the data provider encrypts and hides the entire original data using a random mask and an error vector, and the secret number being a secret number associated with the public key vector and the random mask, encrypted and hidden using random error; receiving data feedback information sent by the data provider, the data feedback information including the secret vector and the secret number; and determining the request result corresponding to the anonymity request from the data feedback information based on the privacy vector. This approach can resist quantum computing attacks and prevent data leakage.
