Abstract
One embodiment provides a computer-implemented method for providing controlled access to electronic content. A password is associated with electronic content, such as by password-protecting an electronic file that contains the electronic content. At least one password attempt is received in an effort to access the electronic content. Each password attempt is compared to the password at a selected subset of “trap” character positions. Up to a threshold number of password entries is allowed that have incorrect characters at any of the trap character positions. A greater number or even an unlimited number of incorrect password entries are allowed having incorrect characters at non-trap character positions. Access to the electronic content is allowed only if one of the password entries exactly matches the password.
