Present disclosure provides a method for determining if an event relates to an unauthorized subject, the method comprising: determining a likelihood of how the event is similar to at least one of: (i) at least one event of a list of events relating to the unauthorized subject and (ii) at least one of a list of events relating to an authorized subject, each event of the list of events comprising data identifying the unauthorized subject, the determination of likelihood being based on the data identifying the unauthorized subject; and determining the event to relate to the unauthorized subject in response to the determination of the likelihood.

Determining if an event relates to an unauthorized subject

Present disclosure provides a method and a server for adaptively updating a target subject identification to be stored in a database, the target subject identification pertaining to a target subject in a system comprising a plurality of servers, the server configured to: receive target subject information; assign a first target subject identification to the target subject information and store the first target subject identification in a first database of the server; and send a request, to the plurality of servers, to synchronize the target subject identification, the request including the target subject information relating to the target subject.

Method and server apparatus for adaptively updating a target subject identification stored in a database

In one aspect, a method includes receiving an image of a target subject; determining a direction in response to the receipt of the image, the direction being one in which the target subject was likely to move during a time period in the past or is likely to move during a time period in the future; determining a target area within which another image of the target subject can be expected to appear based on the determined direction; and determining if a portion of a subsequent image is outside the determined target area to identify if the subsequent image is one relating to the target subject, wherein the subsequent image is one taken during the time period in the past or during the time period in the future.

Method of identifying a target subject, apparatus and non-transitory computer readable medium

The method comprising determining a set of coordinates each for two or more appearances of a target subject within a sequence of images, the set of coordinates of the two or more appearances of the target subject defining a first path; determining a set of coordinates each for two or more appearances of a related subject within a sequence of images, the related subject relating to the target subject, the set of coordinates of the two or more appearances of the related subject defining a second path; determining one or more minimum distances between the first path and the second path so as to determine at least a region of interest; determining a timestamp of a first appearance and a timestamp of a last appearance of the target subject; and determining a timestamp of a first appearance and a timestamp of a last appearance of the related subject.

Duration and potential region of interest for suspicious activities

Present disclosure provides a method for managing an event to generate an alert indicating a subject is likely to be unauthorized, the event comprising data identifying the subject, the method comprising: within a pre-determined period based on a timestamp at which the event is stored in a cache, detecting a recall event comprising the data identifying the subject, the recall event indicating the subject is not likely to be unauthorized; and removing the event from the cache in response to detecting the recall event comprising the data identifying the subject within the pre-determined period.

Method, an apparatus and a system for managing an event to generate an alert indicating a subject is likely to be unauthorized

There is provided a method for identifying potential associates of at least one target person, the method comprising: providing a plurality of videos; identifying appearances of the at least one target person in the plurality of videos; establishing a plurality of video scenes from the plurality of videos, wherein each one of the plurality of video scenes begins at a first predetermined duration before a first appearance of the at least one target person in the respective video scene and ends at a second predetermined duration after a last appearance of said at least one target person in the respective video scene; determining individuals who appear in more than a predetermined threshold number of the plurality of video scenes; and identifying the individuals as potential associates of the at least one target person.

Method for identifying potential associates of at least one target person, and an identification device

The method for obfuscating a string includes selecting, by a processor, a first string of a first portion of input plain text that does not match a predefined text signature from a set of two or more text signatures. In addition, the method may include identifying, by the processor, a historical string that is similar to the first string from a set of two or more historical strings stored. Further, the method may include generating a first text signature, by the processor, by updating a text signature in the set of two or more text signatures that matches the identified historical string. The first text signature defines a pattern that matches the first string and the identified historical string. The first text signature, by the processor, may be saved to the set of text signatures in the memory.
