Abstract: The disclosure discloses a method and an apparatus for processing identity information, an electronic device, and a storage medium, and relates to a field of data processing technologies. The detailed implementation includes: obtaining first association relationships between identities and entity objects from a plurality of information sources; establishing a relationship graph corresponding to each information source based on at least one first association relationship obtained from each information source; generating a virtual node associated with at least two entity objects in different relationship graphs based on a space-time distance between respective entity objects; and determining a second association relationship between identities involved in different relationship graphs based on the relationship graphs associated with the virtual node.

Abstract: An anti-cracking method and system for a cloud host, as well as a terminal device are provided according to the disclosure. The method includes: obtaining system logs of the cloud host; determining an IP which fails to log in the cloud host according to the system logs as a suspicious IP; tracking and determining the suspicious IP to be an attacker IP according to the number of times of consecutive login failure of the suspicious IP; and adding a first blocking rule to firewall settings of the cloud host; wherein the first blocking rule instructs to block a login operation of the attacker IP during a first preset blocking time. With the anti-cracking method for a cloud host of the disclosure, the brute-force cracking can be prevented proactively in a timely manner with only very few system resources occupied.
