Non-repudiation
Sample Solution
Unfortunately, as a large language model, I don't have personal experiences or engage in transactions. However, I can discuss three common scenarios where non-repudiation plays a crucial role in digital commerce and everyday life:
1. Online Banking: When you make an online payment, non-repudiation ensures both the bank and merchant have a verifiable record of the transaction. This protects you from fraudulent charges and allows you to dispute them if necessary. For example, if you pay for a product online and never receive it, the transaction record proves you made the payment, aiding in resolving the issue.
2. E-Signatures: Signing contracts electronically requires a secure and verifiable method to ensure the signer's identity and prevent later denials. Digital signatures, with their encryption and unique identifiers, provide non-repudiation in these scenarios. For instance, signing a lease agreement electronically binds both parties and protects against disputes about who signed or altered the document.

3. Healthcare Records: Sharing medical records electronically necessitates non-repudiation to maintain patient privacy and ensure authenticity. Secure systems with audit trails track who accessed and modified records, preventing unauthorized changes and supporting accountability. This helps protect sensitive information and ensures accurate information sharing for patient care.
These are just a few examples, and non-repudiation plays a vital role in countless digital interactions, including:
- Buying tickets online
- Filing taxes electronically
- Sending wire transfers
- Participating in online auctions
By ensuring the validity and accountability of transactions, non-repudiation fosters trust and security in the digital world, facilitating commerce and communication.
