“…Algorithms of false and multi-secret steganography presented in this paper may be also applied with connection to the visual secret sharing protocols Ogiela 2010, 2012;Yuan 2014). Obtained secret parts of visual information may be hidden over the communication channel and used for monitoring or authorization procedures in many different application, e.g., electronic currency exchange (Ogiela and Sulkowski 2014), medical images watermarking (Hachaj andOgiela 2012, 2013;Ogiela and Ogiela 2011) or even preventing information leakage in large computer infrastructures used for homeland security purposes .…”

This paper presents the new concepts of multisecret and false digital image steganography. The main idea of such approaches is to embed in a single container (digital image) more than one message. The hidden secrets are called real and false messages, respectively. The first one contains essential data which are intended to be securely transferred between different parties, the latter is a bait for focusing attention on an unimportant message. This false and multi-secret steganography will be broken when existence of the real message is revealed, it does not matter whether the false message is detected. Such concepts may find many different applications, especially in situations where communication channel between a sender and a receiver is closely monitored and the warden suspects that the steganography is used. In that case it is probable that the transmitted data will be analyzed in a very detailed way. The concepts described in this paper can help to overcome this problem by dropping a fabricated message and thereby deceiving the warden. The possibility of sending both real and false information at the same time can be seen as additional benefit. In fact, the presented idea allows to establish a kind of subliminal channel while transferring hidden information using digital images. Communicated by V. Loia.

This publication presents some techniques for insider threats and cryptographic protocols in secure processes. Those processes are dedicated to the information management of strategic data splitting. Strategic data splitting is dedicated to enterprise management processes as well as methods of securely storing and managing this type of data. Because usually strategic data are not enough secure and resistant for unauthorized leakage, we propose a new protocol that allows to protect data in different management structures. The presented data splitting techniques will concern cryptographic information splitting algorithms, as well as data sharing algorithms making use of cognitive data analysis techniques. The insider threats techniques will concern data reconstruction methods and cognitive data analysis techniques. Systems for the semantic analysis and secure information management will be used to conceal strategic information about the condition of the enterprise. Using the new approach, which is based on cognitive systems allow to guarantee the secure features and make the management processes more efficient.Index Terms-Cognitive systems, cryptographic data splitting algorithms, insider threats, secure information management.

“…For secure communication when transmitting personal information, pattern information or information access keys, it was designed to be encrypted in two or three layers in the form of cipher-chaining. This also ensured that secret keys were used in the form of chaining or a secret sharing method was used, instead of processing the information using a shared secret key [19,20]. Lastly, when information is accessed, whether the user is a legitimate user is constantly verified.…”

Design of a Distributed Personal Information Access Control Scheme for Secure Integrated Payment in NFC

At the center of core technologies for a future cyber world, such as Internet of Things (IoT) or big data, is a context-rich system that offers services by using situational information. The field where context-rich systems were first introduced is near-field communication (NFC)-based electronic payments. Near-field Communication (NFC) integrated payment services collect the payment information of the credit card and the location information to generate patterns in the user's consumption or movement through big data technology. Based on such pattern information, tailored services, such as advertisement, are offered to users. However, there is difficulty in controlling access to personal information, as there is a collaborative relationship focused on the trusted service manager (TSM) that is close knit to shared personal information. Moreover, in the case of Hadoop, among the many big data analytical technologies, it offers access control functions, but not a way to authorize the processing of personal information, making it impossible to grant authority between service providers to process information. As such, this paper proposes a key generation and distribution method, as well as a secure communication protocol. The analysis has shown that the efficiency was greater for security and performance compared to relation works. OPEN ACCESSSymmetry 2015, 7 936
