“…The AIR was proposed by Hong et al [10] in 2018. The concept of the AIR technique comes from the palette reordering [45], [46], and it rearranges the standard indices to make their spatial correlations stronger.…”

“…However, if we construct another form of index table in an appropriate way, for example, a difference-index table which made up of the differences between adjacent indices, more redundancy might generate from it. There are some existing schemes that utilize the difference values between adjacent indices to hide secret data in a standard-index table, such as [10], [23], [24], [43], [44]. In schemes [23], [24], [43], [44], the difference values are first generated by employing their distinct strategies.…”

“…For each case, the variablelength of secret bits is embedded by encoding the index as a code stream, which is generated by concatenating the indicator and secret data or the binary representation of difference value. In [10], the AIR technique is employed to find a transformed standard-index table, thus making the neighboring indices have similar values. Meanwhile, a weight-controlled least square estimator is employed for prediction, and the indicators are better assigned according to the prediction errors.…”

In this paper, two reversible data hiding (RDH) methods for vector quantization (VQ)-compressed images are presented. In the first method, the difference-index table instead of the standard-index table is designed, and all difference indices are then classified into two groups, i.e., the tobe-mapped group and the candidate group, according to the occurrence frequencies of them. Afterwards, the mapping table between those two groups is adaptively constructed and used to serve for data embedding. Furthermore, another joint method is conducted by combining the standard-index based method and the difference-index based method, resulting in a better embedding performance. The experimental results confirm that both proposed methods, especially the joint method, are significantly superior to the most recent schemes in terms of the embedding capacity, bitrate and embedding rate. INDEX TERMS Reversible data hiding, vector quantization, difference index, mapping.

“…To reduce distortion, quantization levels are recalculated, which, together with bitmaps, encode blocks of pixels after compression. The authors of [132] propose a novel lossless data hiding method for vector quantization (VQ) compressed images. This method combines index reordering and index prediction and reduces the size of compressed files.…”

In Tomsk University of Control Systems and Radioelectronics (TUSUR) one of the main areas of research is information security. The work is carried out by a scientific group under the guidance of Professor Shelupanov. One of the directions is the development of a comprehensive approach to assessing the security of the information systems. This direction includes the construction of an information security threats model and a protection system model, which allow to compile a complete list of threats and methods of protection against them. The main directions of information security tools development are dynamic methods of biometrics, methods for generating prime numbers for data encryption, steganography, methods and means of data protection in Internet of Things (IoT) systems. The article presents the main results of research in the listed areas of information security. The resultant properties in symmetric cryptography are based on the properties of the power of the generating functions. The authors have obtained symmetric principles for the development of primality testing algorithms, as discussed in the Appendix.Symmetry 2018, 10, x FOR PEER REVIEW 3 of 33 Ported to AMR system devices, IPsec ensures mutual authentication of network devices using the IKEv2 protocol. Optionally, the network can be configured based on the EAP-PSK protocol. During configuration, the devices receive network addresses and authentication keys, at which point the execution of EAP-PSK is stopped and data is transferred via IPsec. Another option is to use pre-installed certificates on the devices. In this case, the initial configuration is done manually, but the network does not require EAP-PSK to be used.Data integrity control and encryption during transmission are provided by ESP, which is the protocol used in IPsec at the transport level. This protocol ensures the security of both the data transmitted and packet headers at the network level.This approach makes it possible to ensure reliable authentication of the AMR system devices and the security of the data to be transmitted and opens a wide range of options for the configuration of network operation; however, it cannot be used in networks with heterogeneous communication channels. The EAP-PSK-based approach offers less flexibility but is suitable for networks with heterogeneous communication channels. For an AMR system, a list of threats was proposed based on the developed methodology. Threats to the confidentiality of the system are threats related to the collection of information about the system. This can be a list of devices, software versions, authentication data, access control policies, network addresses, interaction protocols, etc. Threats to the integrity of the automated system for commercial accounting are: substitution of an object, substitution of a communication channel, deletion of an object, destruction of a communication channel, addition of an unauthorized object, creation of an unauthorized communication channel; change of communication channel or object settings...
