Abstract
Computer systems and methods in various embodiments are configured for improving the security and efficiency of server computers interacting through an intermediary computer with client computers that may be executing malicious and/or autonomous headless browsers or “bots”. In an embodiment, a server computer system that is programmed to validate requests from a client computer to a server computer, the server computer system comprising: a memory persistently storing a set of server instructions; one or more processors coupled to the memory, wherein the one or more processors execute the set of server instructions, which causes the one or more processors to: generate a first challenge credential to be sent to the client computer, wherein the first challenge credential corresponds to a first response credential in a first challenge-response credential pair; render one or more first dynamic-credential instructions, which when executed by the client computer, cause the client computer to generate the first response credential in the first challenge-response credential pair; send, to the client computer, the first challenge credential and the one or more first dynamic-credential instru…
