The article deals with topical issues of literary studies related to the definition of the genre specificity of detective literature, which is unique and has an extraordinary prevalence of «mass literature»; the processes of transformation of the genre of detective novel is taken into account. It acquires in the second decade of the XXI century «hybrid forms», which emphasizes the novelty of the material presented in the article. The author raises questions of the history of the genre, analyzes its morphology, conducts research of contact and typological convergence, gives a detailed definition of «genre», which is the subject of study not only literary studies, but also linguistics and «detective». The article describes the ways of development of the modern detective, its main genre-forming features, structural, compositional and plot features.

Today, there is a full development of the food industry. It is characterized by the widest mechanization and automation of production and transport processes, the use of artificial cold and vacuum technology, the latest physical methods, chemical and biological preparations to accelerate technological processes. There are a huge variety of new products. New ways of long-term preservation of products in hermetic airtight packaging are promising. Now it is possible to deliver products from almost any industry to anywhere in the world. But the main problem for the modern consumer is that today's food industry is moving by leaps and bounds in the application and addition of chemical food additives: preservatives, flavors, dyes, stabilizers, antioxidants and substitutes for raw materials. To correctly answer the question of how to treat the use of food with food additives, it is necessary to understand and weigh the main disadvantages and advantages of using them. Advantages are that the product is better preserved, has an attractive appearance. Disadvantages are that the human body wears out, processing various chemicals, it is harmful to health. And with certain doses of use it becomes dangerous. Everyone has their own attitude to their health and their own priorities in life. Many people have come to terms with the daily use of products with additives, but others consciously refuse almost everything in the store. But the fact that no one wants to be poisoned from an overdose of various chemicals or starve to death. Therefore, the main advice is to carefully study the composition indicated on the label of food products and know the measure of their consumption. It is also impossible to believe blindly that the label was written with the truth. Manufacturers often use additives literally visually, which can lead to the production of a product with a dangerously higher concentration. It also happens that the manufacturer intentionally exceeds the norm in order to hide the shortcomings of the product (stale, poor quality of raw materials) and increase the yield of the finished product. The food additives added to many foods (usually designated by the code E) are predominantly harmful to the body. With moderate consumption, the use of products with E-supplements is not too harmful to the body (for example, several times a month). The situation is dangerous when a person consumes products with a large number of food additives daily or even several times a day when using various products. Nowadays, there are several hundred food additives with the code E (from E100 to E1521).

The article presents the results of implementing a quality management system at the enterprise. The study and analysis of the international standard ISO 9001:2015, as well as sanitary and epidemiological requirements for production control were carried out. The main requirements and rules for the implementation of input, operational and output control of products at enterprises at all stages of the product life cycle were identified and presented. In addition, it was determined what requirements must be met by enterprises to implement a quality management system. It is important to note that this work is necessary at the enterprise, as it has the following advantages: by improving product quality, product sales increase, the level of management of the enterprise and personnel increases, and cost savings are realized at the stages of development, production and operation. It follows that to implement a quality management system, it is necessary to set the following tasks: describe the company's processes, develop performance criteria and evaluate processes, develop the necessary documented information, implement documentation in all departments, familiarize them with the quality policy and goals, conduct timely internal audits for further SWOT analysis, and conduct an assessment by an external auditor in order to obtain a certificate of compliance. An important step in quality management is that the organization should not eliminate nonconforming results of processes, but should identify potential nonconformities, assess the risk with the preparation of a Protocol, plan and implement actions to reduce risks. Difficulties may arise: lack of understanding by the staff of the need to implement a quality management system, lack of a clear vision, mission, lack of complete information on processes, lack of quantitative and qualitative evaluation criteria, quality is defined as the quality of products, not as the quality of processes, resources, lack of monitoring of customer satisfaction. It is possible to overcome these difficulties only with the implementation of the quality management system according to ISO 9001, since the requirements prescribed in the international standard are a real tool for improving the efficiency of the enterprise, which will help bring the organization to a higher level of development.

The main problem: The article deals with the issues of hiding text information in a graphic file. A formula for hiding text information in image pixels is proposed. A steganography scheme for embedding secret text in random image pixels has been developed. Random bytes are pre-embedded in each row of pixels in the source image. As a result of the operations performed, a key image is obtained. The text codes are embedded in random bytes of pixels of a given RGB channel. To form a secret message, the characters of the ASCII code table are used. Demo encryption and decryption programs have been developed in the Python 3.5.2 programming language. A graphic file is used as the decryption key. Purpose: To develop an algorithm for embedding text information in random pixels of an image. Methods: Among the methods of hiding information in graphic images, the LSB method of hiding information is widely used, in which the lower bits in the image bytes responsible for color encoding are replaced by the bits of the secret message. Analysis of methods of hiding information in graphic files and modeling of algorithms showed an increase in the level of protection of hidden information from detection. Results and their significance: Using the proposed steganography scheme and the algorithm for embedding bytes of a secret message in a graphic file, protection against detection of hidden information is significantly increased. The advantage of this steganography scheme is that for decryption, a key image is used, in which random bytes are pre-embedded. In addition, the entire pixel bits of the container image are used to display the color shades. It can also be noted that the developed steganography scheme allows not only to transmit secret information, but also to add digital fingerprints or hidden tags to the image.
