Software Release Verification via Stage Digital Signatures

The patent implements preliminary verification by generating digital signatures at each development stage before deployment. These signatures are created in advance and attached to the software release, allowing the deployment system to verify completion of required stages without delaying the deployment process. The verification data is prepared beforehand, enabling fast deployment while maintaining security.

The patent uses digital signatures as simplified copies or representations of the complex verification process. Instead of implementing complex verification logic at each deployment node, the system creates compact digital signature copies that encapsulate the verification state. These signatures can be easily transmitted and verified using standard cryptographic operations, reducing system complexity while maintaining high verification reliability.

Digital signatures are generated in advance at each development stage during the build process, rather than being created at deployment time. This preliminary generation allows the actual deployment to proceed quickly, as the verification process only needs to validate pre-generated signatures. The time investment is made during development stages when processing is already occurring, minimizing impact on deployment speed.
