A method for allowing user access to a resource includes a large number of arrays of elements which are generated and stored for each user for use in a series of log-in sessions. A user input token is calculated by identifying a subset of the array by a pattern of the elements in the array, combined in an operation on the elements selected using one or more mathematical, relational and/or logical operations. The arrays are stored in a table with the tokens calculated from those arrays and withdrawn in a random pattern for use in the sessions for that user. Each array includes multiple possible solutions including the actual solution using the pattern and calculation of that user and these other possible solutions act as hacker traps to indicate the presence of a hacker who has calculated a solution but found the wrong solution |
