Abstract:
1. A computer program product comprising a non-transitory computer useable storage medium to store a computer readable program for implementing graduated difficulty for a human response test to differentiate between a human response and a computer response, wherein the computer readable program, when executed on a computer, causes the computer to perform operations comprising: initiating a first human response test with a designated level of difficulty at a source computing device in response to a first test request, wherein the first test request comprises a first source identifier to identify at least one characteristic of the source computing device; recognizing a second test request subsequent to the first test request, wherein the second test request comprises a second source identifier, wherein the second test request occurs after receiving a correct response to the first human response test and after granting requested access of the first test request; initiating a second human response test in response to the second test request, wherein the second human response test has a level of difficulty which is dependent on a determination whether the first and second source identifiers correspond to the same source computing device; and wherein the first human response test is associated with a first difficulty identifier indicative of a first level of difficulty, and the second human response test is associated with a second difficulty identifier indicative of a second level of difficulty, wherein the second level of difficulty is more difficult than the first level of difficulty in response to the determination that the first and second source identifiers correspond to the same source computing device.
