Meaning
Information security practices manage the possession and access rights of the original design data used to create a product. Proper source file custody ensures that the firmware code and physical layout files remain under the control of the owner during the manufacturing process. This protection prevents unauthorized modifications and the theft of intellectual property.
Ownership Transfer
Documented logs track every person who views or downloads the sensitive files from a server. In the context of source file custody, restrictive permissions prevent an assembly house from accessing the core logic of a device without a specific business need. Audits of these logs confirm that the data remained secure throughout the contract.
Access Audit
Secure servers or encrypted physical drives provide the path for moving data between the designer and the factory. When a technician handles a file transfer under source file custody, the use of cryptographic hashes verifies that the data has not been altered. This maintains the integrity of the build.
Integrity Validation
Legal agreements define who owns the files and what the manufacturer can do with them after the project ends. Source file custody requires the return of all data copies once the production run is finished. Clear terms prevent the factory from using the design for other customers.
