Abstract
A method of increasing the security of image transmission in messengers using one-time passwords
Incoming article date: 04.12.2024The article presents a method for protecting transmitted images in instant messengers using time-based one-time passwords (TOTP). An additional level of protection is offered based on a combination of image masking using orthogonal matrices and two-factor authentication based on TOTP. A prototype Python application has been developed and tested using the gRPC remote procedure protocol to ensure secure data exchange between the client and the server. The results of the implementation of the proposed method in preventing unauthorized access to confidential images are presented.
