To determine whether digital content can be released to an element such as a computer application or module, a scaled value representative of the relative security of the element is associated therewith, and the digital content has a corresponding digital license setting forth a security requirement. The security requirement is obtained from the digital license and the scaled value is obtained from the element, and the scaled value of the element is compared to the security requirement of the digital license to determine whether the scaled value satisfies the security requirement. The digital content is not released to the element if the scaled value does not satisfy the security requirement.
