Undeniable signatures are a form of digital signature invented by David Chaum and Hans van Antwerpen in 1989. They have two distinctive features, The verification process is interactive, so that the signatory can limit who can verify the signature. A disavowal protocol, which is a cryptographic protocol that allows them to determine whether a given signature is a forgery . The first means that a signatory can allow only others who are authorized to access the document to verify their signature. If the document were to be leaked to a third party, the third party would be unable to verify that the signature is genuine. This is a designated verifier signature . However, because of this property it means that the signatory may deny a signature which was valid. To prevent this, there is the second property, a method to prove that a given signature is a forgery.

cleanup date December 2011 In computer science , a signature file is a technique applied to document retrieval . The idea behind signature files is to create a quick and dirty filter that will keep all the documents that match to the query and hopefully a few ones that do not. The way this is done is by creating for each file a signature, typically a hash coded version. One method is superimposed coding. A post processing step is done to discard the false alarms. Since in most cases this structure is inferior to inverted file s in terms of speed, size and functionality, it is not used widely. However, with proper parameters it can beat the inverted files in certain environments.

The prime signature of a number is the multiset of exponents of its prime factorisation . For example, all prime number s have a prime signature of 1 , the squares of primes have a prime signature of 2 , the products of 2 distinct primes have a prime signature of 1,1 and the products of a square of a prime and a different prime e.g. 12,18,20,... have a prime signature of 2,1 . The number of divisor s that a number has is determined by its prime signature as follows If you add one to each exponent and multiply them together you get the number of divisors including the number itself and 1. For example, 20 has prime signature 2,1 and so the number of divisors is 3x2 6. They are 1,2,4,5,10 and 20. The smallest number of each prime signature is a product of primorial s. The first few are 1, 2, 4, 6, 8, 12, 16, 24, 30, 32, 36, 48, 60, 64, 72, 96, 120, 128, 144, 180, 192, 210, 216, ... OEIS id A025487 .

Unreferenced stub auto yes date December 2009 File Spectrum of blue sky.svg thumb 300px right Spectrum of blue sky Spectral Signatures are the specific combination of reflected and absorbed electromagnetic radiation electromagnetic EM radiation at varying wavelengths which can uniquely identify an object. The spectral signature of stars indicates the spectrum according to the EM spectrum. The spectral signature of an object is a function of the incidental EM wavelength and material interaction with that section of the electromagnetic spectrum . The measurements can be made with various instruments, including a task specific spectrometer , although the most common method is separation of the Red, Green, Blue and Near Infrared portion of the EM spectrum as acquired by digital cameras. Calibration of spectral signatures under specific illumination are collected in order to apply an empirical correction to airborne or satellite imagery digital images. When using a spectrometer, you will look through it at a tube of gas with high voltages passing through it. In the Spectrometer, you will be able to see specific rays of colour falling on graduations on the inside. Each substance will have its own unique falling of rays. Most remote sensing applications process digital images to extract spectral signature at each pixel and use such signature to divide the image in groups of similar pixels Segmentation image processing segmentation using different approaches, and, as last step, assign a class to each group classification by comparing with known spectral signatures. Depending on pixel resolution, a pixel can represent many spectral signature mixed together that is why a lot of remote sensing analysis is done to unmix mixtures . Ultimately correct matching of spectral signature recorded by image pixel with spectral signature of existing elements leads to accurate classification in remote sensing.

A signature crime is a crime which exhibits characteristics idiosyncratic to specific criminal s, known as signature aspects , signature behaviours or signature characteristics . Where a modus operandi MO concerns the practical components of a crime which can also be unique to one suspect, signature aspects fulfill a psychological need and, unlike the MO, does not often change. Two examples cited in Crime Classification Manual by John Douglas are a bank robber from Michigan who required tellers to undress during the robbery so he could photograph them, and a rape case where the perpetrator forced the husband to return home and be humiliated by the event. These characteristics move beyond modus operandi, because they fulfill a psychological need rather than a need of practical execution of the crime. ref cite book last Douglas first John title Crime Classification Manual publisher John Wiley and Sons year 2006 edition 2nd edition pages 23 24 isbn 0787985015 ref The 1898 Gatton murders also exhibited signature aspects.

In cryptography , a ring signature is a type of digital signature that can be performed by any member of a group of users that each have key cryptography keys . Therefore, a message signed with a ring signature is endorsed by someone in a particular group of people. One of the security properties of a ring signature is that it should be difficult to determine which of the group members keys was used to produce the signature. Ring signatures are similar to group signature s but differ in two key ways first, there is no way to revoke the anonymity of an individual signature, and second, any group of users can be used as a group without additional setup. Ring signatures were invented by Ron Rivest , Adi Shamir , and Yael Tauman , and introduced at ASIACRYPT in 2001. ref http www.springerlink.com ... 2001. ref The name ring signature comes from the ring like structure of the signature algorithm ... signature on a message m , on input m , SK sub i sub , PK sub 1 sub , ... , PK sub n sub .
