Ann, a software developer, wants to publish her newly developed software to an online store. Ann wants to ensure that the software will not be modified by a third party or end users before being…

Single sign-on is an authentication mechanism enabling users to access multiple services with one credential set; it does not measure or verify the integrity of software code.

Identity propagation passes authenticated user identity across application boundaries but does not inspect or validate the cryptographic integrity of software binaries.

Remote attestation uses cryptographic measurements of software code and configuration - typically anchored in a Trusted Platform Module (TPM) - to generate a hash that is compared against the developer's known-good signed value. If the measurement does not match the expected baseline, the platform refuses to load or execute the software. This mechanism directly addresses Ann's requirement by detecting any third-party or end-user modifications before the application is allowed to run on mobile devices.

Secure code review is a development-phase practice for identifying vulnerabilities in source code; it does not prevent the runtime execution of modified compiled binaries after distribution.
