FIELD: computer equipment.
SUBSTANCE: invention relates to a method and a device for providing a signal indicating loss of a terminal. To achieve the technical result, obtaining a match relationship between the first distinctive information of the current user of the target terminal and the second distinctive information of the predetermined user of the target terminal and instructing the interfaced terminal associated with the target terminal to issue a loss signal in response to determining that the match ratio indicates that the first distinctive information and the second distinctive information do not match. Loss signal contains at least one information from information on the current location of the target terminal and the distinctive information of the face of the current user. If the server determines that the current user of the target terminal differs from the predetermined user of the target terminal, this indicates that the target terminal could be lost, and it is necessary to instruct the conjugate terminal of the target terminal to issue a loss signal in order to enable the owner of the target terminal to timely learn about loss of the target terminal by means of a loss signal issued by the conjugate terminal, and to take appropriate measures as soon as possible.
EFFECT: possibility of the owner of the target terminal to detect the lost target terminal.
