Abstract
A method is provided for protecting an on-line resource using a HIP challenge. The method includes receiving a request to access the on-line resource from a remote client. A HIP challenge is presented to a user associated with the remote client. If a successful response to the HIP challenge is received from the user, a previous response pattern of the user is compared to known response patterns of humans and machines. The user is allowed to access to the on-line resource if the comparison indicates that the user is likely a human.
