In the context of Computer Science, based on the provided reference, Computer Verification, specifically referring to a 'Verification Process', is defined as a process that compares an input sample with a stored template (prototype) in a database.
Understanding the Computer Verification Process
This process serves to confirm the identity or authenticity of an input by checking it against pre-existing, reliable data. The system holds one or more stored templates or prototypes within a database. When an input sample is received, the verification system performs a comparison between this input and the stored templates.
The outcome of this verification process is determined by the success of these comparisons. According to the definition, the system evaluates the verification result as positive if there is at least one successful comparison between the input sample and any of the stored templates. This means the input is deemed to match one of the authorized or expected prototypes held in the database.
Key Components of the Verification Process
The fundamental elements involved in this type of computer verification include:
- Input Sample: The data that is being presented to the system for verification. This could be an image, a data string, a biometric scan, etc.
- Stored Template (Prototype): A pre-recorded or stored representation of authorized or expected data held within the database.
- Database: The repository where the stored templates are kept.
- Comparison: The computational step where the input sample is analyzed and matched against the stored template(s).
- Positive Result: Achieved when the comparison finds a sufficient match between the input sample and at least one stored template.
Practical Examples
This definition of computer verification aligns with processes commonly used in identity confirmation and data matching systems:
- Biometric Verification: Comparing a scanned fingerprint, face, or iris (the input sample) against stored biometric templates in a database to confirm identity.
- Signature Verification: Matching a scanned signature (the input sample) with stored prototype signatures.
- Simple Data Matching: Comparing an entered ID number or code (the input sample) against a list of valid entries (stored templates) in a database.
Essentially, this type of computer verification is a matching process where an incoming piece of data is checked against known, authorized data points.
