Abstract: A method and system for securing data of biotechnological laboratories using blockchain technology, including a central server and two or more subsystems controlled by a dedicated sub-server. Each of the two or more subsystems includes: a first blockchain database for storing information data, a second blockchain database for storing access data, wherein users having access to the first database are able to allow or forbid another user to read from the first database the data authored by them by adding the digital key of said another user with information of corresponding permissions to the second database. Every authorized user having access to the first database is able to revoke from another user previously granted access to data in the first database, and said method for securing data includes verification by the central server of compatibility and immutability of blockchain databases in said two or more subsystems.

Abstract: A method for analysing microscopic images of a blood smear allowing to determine the number of thrombocytes in a tested sample. The present disclosure uses an algorithm which allows for differentiating between platelets from other blood cells (including erythrocytes), and then counts the quantity of thrombocytes (number/?l) and determines their size (?m). The method includes providing a grayscale microscopic image of platelets, segmenting and analysing the image, wherein the step of segmentation and analysis of the image comprises analysing light regions of the image and analysing dark regions of the image, including detecting distinctive regions in the image using a maximally stable external regions algorithm; calculating for each light and dark region identified its convex hull and filtering the results obtained by shape; removing nesting regions; identifying aggregates; classifying cells into platelets and other blood constituents; and determining the number of platelets and masks thereof.
