Type: article
Abstract: This work offers an overview of the possibilities of using bacteriorhodopsin in modern information securitysystems. The main areas of application include methods of protecting and marking printed documents, use in data andpersonnel authentication systems, optical recording and storage of digital information with additional protection options.Bacteriorhodopsin-based materials allow the creation of high-speed cryogenic high-capacity storage devices. Allinformation on these devices is irreversibly erased when the media is heated to room temperature, when secret datarequires lability to prevent unauthorized access. The use of bacteriorhodopsin films for polarization recording ofinformation, in addition to the high capacity of the medium, complicates unauthorized copying, allows the use of reliableencryption during recording and easy implementation of multiplexing of several data sets on one medium. The propertiesof bacteriorhodopsin allow direct laser recording of individualized computer-generated holograms without the use oftemplates, which facilitates its use together with other means of protection. The photochromic properties ofbacteriorhodopsin can be exploited to develop inks that undergo color changes upon light irradiation, while modificationof its amino acid sequence may serve as a hidden genetic marker for tracking and authenticating batches of documents.Various protection methods can be integrated on one carrier, examples of which are also described in the work. This workdemonstrates the significant potential of native bacteriorhodopsin in information security systems, provides an analysis of world literature in this area, summarizes the results of many years of research by the authors, and outlines currentproblems and options for their solution in the future.Keywords: bacteriorhodopsin, photocycle, film structures, photochromism, polarization recording, informationsecurity, information protection.
