“…As a result, the consciousness of ancient man built a system of the internal organisation of the surrounding world -an ordered network of dualistic representations, which in the process of human awareness of their individuality, caused the division of reality into two spaces -"friend", in which everything was familiar and understandable, and "foe", which was unknown and posed a threat. In the context of the proposed study, it is important to consider the ethnocentric worldview of ancient Ukrainians, for whom the identification of one's geographical space was the basis for the 'friend -foe' opposition (Singh et al, 2016;). The validity of this statement is proved by the fact that the word Ukrainians itself, as the ancient name of the inhabitants of the Dnieper region, which played an integral role in the development of the Ukrainian people and their language, has 'friend' seme in its meaning, which follows from the interpretation of the lexeme Ukraine.…”

"friend-foe" opposition in Ukrainian linguoculture

The friend – foe dichotomy, as a special way of categorising reality, is at the heart of ethnic self-consciousness, building the world around a person. The interpretation "friend" and "foe" is invariably axiological. "Friend" refers to a personal possessor, a socio-cultural group that is identified based on various types of similarity, where "correct", "native", "close", "safe" is perceived as positive. The conceptual model "foe" is the opposition: everything "other", "strange", "unusual", "wrong" is perceived negative. The axiologiness of this opposition is relative and depends on the ethical attitudes of an ethnic group based on the conceptualisation of the friend – foe dichotomy from the standpoint of the binary opposition I – Other; the factors, mechanisms, and results of interaction between the components of the opposition are clarified; the content transformations of the friend – foe dichotomy are traced; the identification function of the latter is updated in the context of modernity. For Ukraine, where the identity development has happened to be incredibly complicated by the incongruity of value, foreign, and political orientations, the issue of borderline, "border strategies", the presence of the "friend" / "foe" dichotomy in the socio-cultural space is extremely relevant.

“…An essential necessity for offering e-health services is, the transmission of medical images over the network and the storing of these images in databases. Patients in e-health services like tele-medicine, Telediagnosis, and Tele-radiology applications have a serious and expanding problem with the identification and authenticity of medical images [1,2]. To avoid inaccuracy in medical diagnosis and tele-medicine applications, accurate identification of medical images and proper patient verification are critical requirements.…”

In recent years the combination of medical image watermarking and encryption is becoming popular due to a better trade-off between authenticity and security, since, each of these methods alone is insufficient to offer complete security. In the proposed work,the watermark is embedded into the Fundus image using the Singular Value Decomposition (SVD) of the La*b* space image of the Fundus image. The scaling factor is selected based on the HVS property of the human eye. The proposed embedding algorithm is semi-blind because the system requires the singular values (s) of the La*b* image at the receiver side in order to extract the watermark. To improve security, the authenticated image then undergoes 2-levels of confusion process followed by diffusion for encryption. For diffusion, the key is generated from the newly developed Modified Sine-Logistic Chaotic System (MSLCS), which is constructed by the combination of logistic map and sine map. The performance evaluation of the new chaotic system has been done in terms of the Bifurcation diagram, Lyapunov exponent, Phase portrait and Entropy. Also, Different tests such as Blood vessel segmentationand Retinal object identification were carried out on the original image, watermarked image, decrypted image and recovered image. The results show that the embedding of watermarks followed by encryption, on Fundus images does not affect the diagnosis and identification of retinal objects. Correct decryption, secured recovery of Fundus image and guaranteed extraction ofthe watermark at the receiver side make the proposed system secure for Fundus images in tele-ophthalmology applications.

“…In [21], the authors indicate that the number and the angles of major blood vessels in the area of the optic disc, their way to emerge from the optic nerve, the branching characteristics of the blood vessels and the size of the optic disc are unique. The proposed method leads to segment blood vessels in the region near to OD in order to generate unique identification code.…”

“…Based on described works in section 3, most biometry method based on retinal images proceed to segment OD and blood vessels. the vessel tree is considered as unique component which is used to authentication [21,16,23]. Other works extract bifurcations and ending points from blood vessels which are considered as personal unique features [19,24].…”

In this chapter, retinal image processing will be addressed as a Hidden Biometric modality. Considered as safe modalities, the retinal vascular network provide a unique pattern for each individual since it does not change throughout the life of the person. In addition, the retina offers a high level of recognition, which makes it suitable for high security applications thanks to its universality, its invariability over time and its difficulty to falsify.
