Monitoring the invariability of medical images during transmission over communication channels

Relevance. Modern methods of ophthalmic medical examinations, for example, ultrasound biomicroscopy, optical coherence tomography, axial MR tomography, and so on, allow you to save results, medical images in electronic form. The obtained image can be stored and transmitted via communication channels, which allows doctors to easily exchange information about the patient, since all tests are now in a single electronic patient card, as well as conduct long-distance consultations. Accurate diagnosis requires that ophthalmic medical images be protected from alteration, both intentional and accidental, when stored and transmitted over communication channels. Purpose. The goal of this work is to investigate the possibility of using modern digital watermark methods to control the integrity and immutability of stored and transmitted ophthalmic medical images. Material and methods. This article uses the results of a study of accurate authentication algorithms conducted using specially written software that allows you to attach and extract a digital watermark. Results. The possibility of using existing algorithms for embedding digital watermarks in ophthalmic medical images to control the absence of distortion during their storage and transmission has been investigated. Here is an example of accurate snapshot authentication using a digital watermark. Conclusion. The article considers the possibility of accurate authentication of ophthalmic medical images to control their invariability. State-of-the-art digital watermarking algorithms allow for monitoring the immutability of ophthalmic medical images during storage and transmission.
