Electronic signature

Jump to navigationJump to search

An electronic signature, or e-signature, refers to data in electronic form, which is logically associated with other data in electronic form and which is used by the signatory to sign.This type of signature provides the same legal standing as a handwritten signature as long as it adheres to the requirements of the specific regulation under which it was created (IDAS in the European Union, NIST-DSS in the USA or ZertES in Switzerland).

Electronic signatures are a legal concept distinct from digital signatures, a cryptographic mechanism often used to implement electronic signatures. While an electronic signature can be as simple as a name entered in an electronic document, digital signatures are increasingly used in e-commerce and in regulatory filings to implement electronic signatures in a cryptographically protected way. Standardization agencies like NIST or ETSI provide standards for their implementation (e.g., NIST-DSS, XAdES or PAdES).The concept itself is not new, with common law jurisdictions having recognized telegraph signatures as far back as the mid-19th century and faxed signatures since the 1980s.

A patent is a document issued by the government office which describes the invention and creates a legal situation in which the patented invention can normally only be exploited (made, used, sold, imported) by or with the authorization of the patentee. WHAT INVENTIONS ARE PATENTABLE ? An invention is a novel idea which permits in practice the solution of a specific problem in the field of technology. Under most legislations concerning inventions, the idea, in order to be protected by law ("PATENTABLE"), must be new in the sense that is has not already been published or publicly used, it must be "non-obvious" in the sense that it would not have occurred to any specialist in the particular industrial fields, had such a specialist been asked to find a solution to the particular problem and it must be "applicable in industry" in the sense that it can be industrially manufactured or used. WHAT THE PATENT ACT 1983 PROVIDES ? M...

 Cyber Law Week 13 A Taxonomy for Cybercrime Attack in the Public Cloud Public cloud users interact online or offline using natural language. While the language used could be in Xhosa, English, Afrikaans, Zulu or Ndebele, the core component is communication. Therefore, natural language is the language that people speak, listen to and understand. This is the same language that a public cloud user, uses to interact with another human and/or machine components of the public cloud. Meanwhile the same natural language is sometimes used by cybercrime attackers to achieve their aims when targeting users of the public cloud. The targeting of the users could be attributed to the user’s basic knowledge of the public cloud when seeking information or relationship formation, thereby unintentionally revealing points of vulnerabilities that often expose them to cybercrime attacks. A challenge to traditional digital forensic processes in the public cloud environment is the inability to retrieve a...
