Abstract
Embodiments of the present application relate to a method of controlling user risk, a system for controlling user risk, and a computer program product for controlling user risk. A method is provided. The method includes retrieving association data of a first user and association data of a second user, the association data including multidimensional data, and data relating to each dimension identifying a user and serving as an association dimension, based on the association data, computing an association value between the first user and the second user for an association dimension, gathering the association value to obtain a degree of real association, and determining that the other user is malicious.
Claims17
A network virtual user risk control method, comprising:
- retrieving raw association data of a first virtual user and raw association data of a second virtual user, the raw association data comprising multidimensional data, and data relating to each dimension being capable of identifying a user and serving as an association dimension, wherein one of the first virtual user and the second virtual user is deemed to be a malicious user;
- based on the raw association data of the first virtual user and the second virtual user, computing at least one association value between the first virtual user and the second virtual user for an association dimension;
- gathering the at least one association value of the association dimension to obtain a degree of real association between the first virtual user and the second virtual user;
- determining whether the degree of real association between the first virtual user and the second virtual user exceeds a predetermined threshold value;
- and
- determining that the other of the first and second virtual users is a malicious user.
A network virtual user risk control system, comprising:
- at least one processor configured to:
- retrieve raw association data of a first virtual user and raw association data of a second virtual user, the raw association data comprising multidimensional data and data relating to each dimension being capable of identifying a user and serving as an association dimension, wherein one of the first virtual user and the second virtual user is deemed to be a malicious user;
- based on the raw association data of the first virtual user and the second virtual user, compute at least one association value between the first virtual user and the second virtual user for an association dimension;
- gather the at least one association value for the association dimension to obtain a degree of real association between the first virtual user and the second virtual user;
- determine whether the degree of real association between the first virtual user and the second virtual user exceeds a predetermined threshold value;
- and
- determine that the other of the first and second virtual users is a malicious user;
- and
- a memory coupled to the at least one processor and configured to provide the at least one processor with instructions.
A computer program product for controlling network virtual user risk, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:
- retrieving raw association data of a first virtual user and raw association data of a second virtual user, the raw association data comprising multidimensional data, and data relating to each dimension being capable of identifying a user and serving as an association dimension, wherein one of the first virtual user and the second virtual user is deemed to be a malicious user;
- based on the raw association data of the first virtual user and the second virtual user, computing at least one association value between the first virtual user and the second virtual user for an association dimension;
- gathering the at least one association value of the association dimension to obtain a degree of real association between the first virtual user and the second virtual user;
- determining whether the degree of real association between the first virtual user and the second virtual user exceeds a predetermined threshold value;
- and
- determining that the other of the first and second virtual users is a malicious user.
