Improving grayscale steganography to protect personal information disclosure within hotel services

An unauthorized leak of information that is not tolerable always implies inadequate or poor security measures of information. Globally, the hospitality industry has in the recent past been targeted by cybercrimes. Management of cybercrimes are divided into facets like policies of security frameworks, cyber-threats, and management appreciating the value of Information Technology investment. These aspects possess a notable influence on the information security of an organization. This study's purpose is to examine cybersecurity activities of network threats, electronic information, and the techniques of preventing cybercrime in hotels. Helping Chief Information Officers (CIO) and the directors of information technology is the main aim of the research to improve policy for electronic information security in the hospitality industry and recommending several tools and techniques to stabilize the network of computers. Further, to protect personal information disclosure for the visitors, an information hiding technique has been proposed by utilizing the least significant bits (LSBs) of each pixel of grayscale image adopting XOR features of the host image (HI) pixels. Also, the proposed technique successfully withstands various steganalysis attacks like regular and singular (RS) attack, pixel difference histogram (PDH) attack, and subtractive pixel adjacency matrix (SPAM) steganalysis.
