Abstract
Aspects relate to determining whether a security token has previously been used in order to gain access to premium content. When a security token is received, the token is evaluated to determine whether the token has been previously received, which indicates an attempt to reuse the token. If the token was previously received, the token is rejected and access to the premium content is denied. If the token was not previously received, the token is analyzed by a third party verification process. If the third party verification process authenticates the token, access to the premium content is granted. With the disclosed aspects, a security vulnerability related to reuse of a security token can be mitigated.
