Scottish Intercollegiate Guidelines Network

The Scottish Intercollegiate Guidelines Network (SIGN) is a part of Healthcare Improvement Scotland, the national healthcare improvement organization for Scotland. SIGN develops evidence-based clinical practice guidelines for the National Health Service (NHS) in Scotland. These guidelines are used by healthcare professionals to make decisions about care and treatment. SIGN guidelines cover a wide range of medical, surgical, and mental health conditions.

Digital Signature

In cryptography, to SIGN a document or message means to apply a digital signature. This is a mathematical scheme for demonstrating the authenticity of a digital message or document. A valid digital signature gives a recipient reason to believe that the message was created by a known sender and that it was not altered in transit.

Sign Language

In linguistics, a SIGN is a unit of meaning in a sign language. Sign languages are languages that use the visual-manual modality to convey meaning. They are used by deaf communities and can be found all over the world. Each sign in a sign language can consist of a specific combination of location, handshape, movement, and non-manual elements.
