The Wisconsin Digital Signature Ordinance, also known as Signaturverordnung or Sign, is a set of regulations that governs the use and acceptance of digital signatures in the state of Wisconsin. It provides legal recognition and validity to electronically signed documents and transactions, ensuring their authenticity and integrity. Under the Wisconsin Digital Signature Ordinance, individuals and organizations can use digital signatures to sign and authenticate various types of digital documents, including contracts, agreements, and forms. These digital signatures are generated using cryptographic algorithms, ensuring that the signed documents cannot be altered without detection. The Wisconsin Digital Signature Ordinance emphasizes the importance of security and privacy in digital transactions. It outlines the technical requirements for creating and verifying digital signatures, such as the use of secure cryptographic algorithms and encryption methods. It also promotes the use of trusted certificate authorities to issue digital certificates, which bind the identity of the signer to their digital signature. There are several types of digital signatures recognized under the Wisconsin Digital Signature Ordinance. These include: 1. Basic Electronic Signature: This type of digital signature is created using a private key that is exclusively under the control of the signer. It is used to verify the integrity and authenticity of the signed document. 2. Advanced Electronic Signature: In addition to the basic functionality, an advanced electronic signature is uniquely linked to the signer and enables the identification of any subsequent changes made to the signed document. 3. Qualified Electronic Signature: A qualified electronic signature is considered the most secure and reliable form of digital signature. It requires a certificate issued by a qualified trust service provider, ensuring the highest level of trust and compliance with legal requirements. The Wisconsin Digital Signature Ordinance aligns with international standards and best practices for the use of digital signatures. It provides a legal framework to facilitate secure and reliable electronic transactions, enhancing efficiency and reducing costs associated with paper-based processes. By adopting the Wisconsin Digital Signature Ordinance, individuals and businesses in Wisconsin can confidently engage in electronic transactions, with the assurance that their digitally signed documents will be legally recognized and enforceable.
