Unreferenced date October 2008 Fileverification is the process of using an algorithm for verifying the integrity or authentication authenticity of a computer file . This can be done by comparing two files bit by bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files. A more popular approach is to also store checksum s hashes of files for later comparison. Integrity verificationFile integrity can be compromised, usually referred to as the file becoming Data corruption corrupted . A file can become corrupted by a variety of ways faulty storage media , errors in transmission, write errors during copying or moving, software bug s, and so on. hash function Hash based verification ensures that a file has not been corrupted by comparing the file s hash value to a previously calculated value. If these values match, the file is presumed to be unmodified. Due to the nature of hash functions, hash collision s may result in false positive s, but the likelihood of collisions is often negligible with random corruption. Authenticity verification It is often desirable to verify that a file hasn t been modified in transmission or storage by untrusted parties, for example, to include malicious code such as virus es or Backdoor computing backdoor s. To verify the authenticity, a classical hash function is not enough as they are not designed to be collision resistance collision resistant it is computationally trivial for an attacker to cause deliberate hash collisions, meaning that a malicious change in the file is not detected with by a hash comparison.

Intelligent Verification , also referred to as intelligent testbench , is a form of functional verification used to verify that an electronic hardware design conforms to specification before device fabrication. Intelligent verification uses information derived from the design and existing test description to automatically update the test description to target design functionality not verified, or covered by the existing tests. Intelligent verification software has this key property given the same test environment, the software will automatically change the tests to improve functional design coverage in response to changes in the design. Other properties of intelligent verification may include Providing direction as to why certain coverage points were not detected. Automatically tracking paths through design structure to coverage points, to create new tests. Ensuring that various aspects of the design are only verified once in the same test sets.

Functional verification , in electronic design automation , is the task of verifying that the digital circuit logic design conforms to specification. In everyday terms, functional verification attempts to answer the question Does this proposed design do what is intended? This is a complex task, and takes the majority of time and effort in most large electronic system design projects. Functional verification is very difficult it is equivalent to program verification , and is NP hard or even worse and no solution has been found that works well in all cases. However, it can be attacked by many methods. None of them are perfect, but each can be helpful in certain circumstances Logic simulation simulates the logic before it is built. Simulation acceleration applies special purpose hardware to the logic simulation problem. Emulation builds a version of system using programmable logic. This is expensive, and still much slower than the real hardware, but orders of magnitude faster than simulation. It can be used, for example, to boot the operating system on a processor. Formal verification attempts to prove mathematically that certain requirements also expressed formally are met, or that certain undesired behaviors such as deadlock cannot occur.

Analog verification is a methodology for performing functional verification on analog, mixed signal and RF integrated circuits and System on a chip systems on chip . Discussion of analog verification began in 2005 when it started to become recognized that the analog portion of large mixed signal chips had gotten so complex that a significant and ever increasing number of these chips were being designed with functional errors in the analog portion that prevented them from operating correctly. Technical details Analog verification is built on the idea that transistor level simulation will always be too slow to provide adequate functional verification. Instead, it is necessary to build simple and efficient models of the blocks that make up the analog portion of the design and use those to verify the design. Those models are typically written in Verilog or Verilog AMS , but could also be written in VHDL or VHDL AMS . However, simply using a simple functional model is not sufficient. It is also necessary to build a comprehensive self checking testbench, that thoroughly exercises the design and compare its response against a previously written specification for the design. Furthermore, this testbench should be applied in turn to both the model and the design. In this case, the design is represented with a transistor level schematic. If both the model and the design pass all tests, and if the testbench is comprehensive, then this confirms that the model is consistent with the design and that the design is consistent with the specification. Applying a comprehensive testbench to an entire analog functional unit such as an audio codec , power management unit, serdes , or RF transceiver, represented at the transistor level is impractical. So instead, the verification proceeds hierarchically. One first builds simple models and testbenches for individual blocks.

Lenders require complete VOE declaring all positions held for the last two years of employment history. Most mortgages are preceded by both written and verbal VOEs. Once a lender receives the initial loan application, a Written Verification of Employment Form 1005 is sent to all current and previous employers within the last two years listed on the application. This form is filled out by an authorized representative of the employer and includes dates of employment, positions held and a breakdown of Remuneration compensation received. This information is compared to both the loan application and the income documentation, such as W2 s and Payroll Paycheck paycheck pay stub stubs , to ensure the information is correct. Once a mortgage has been approved and the borrowers have signed their mortgage documents, a Verbal Verification of Employment is conducted with all current employers prior to funding the loan. This is done to ensure that the borrower has not stopped working since the application was submitted, which would influence the terms on which the loan was approved. VOE guidelines are different for Self employment self employed borrowers, as a VOE should not be completed by the loan applicant. Self employed borrowers are typically asked to either provide a current business license or, for borrowers who do not have a traditional business model, a letter from their Certified Public Accountant indicating that they have firsthand knowledge of their previous and continued employment as their tax preparer.

Refimprove date September 2009 Physical verification is a process whereby an Integrated Circuit Layout IC layout design is checked via EDA software tools to see if it meets certain criteria. Verification involves DRC Design rule check , LVS Layout versus schematic , ERC Electrical Rule Check , XOR Exclusive OR , and Antenna Checks. XOR Check This check is typically run after a metal spin, where the original and modified database are compared. This is done to confirm that the desired modifications have been made and no undesired modifications have been made by accident. This step involves comparing the two layout databases GDS by XOR operation of the layout geometries. This check results a database which has all the mismatching geometries in both the layouts. Antenna Check The antenna basically is a metal interconnect, i.e., a conductor like polysilicon or metal, that is not electrically connected to silicon or grounded, during the processing steps of the wafer. During the manufacturing process charge accumulation can occur on the antenna during certain fabrication steps like Plasma etching, which uses highly ionized matter to etch. If the connection to silicon does not exist, charges may build up on the interconnect to the point at which rapid discharge does take place and permanent physical damage results to thin transistor gate oxide. This rapid and destructive phenomenon is known as the antenna effect . Antenna errors can be cured by adding a small antenna diode to safely discharge the node or spillting the antenna by routing up to another metal layer and then down again. The Antenna ratio is defined as the ratio between the physical area of the conductors making up the antenna to the total gate oxide area to which the antenna is electrically connected.

Unreferenced stub auto yes date December 2009 The verification theory of meaning is a Philosophy philosophical theory proposed by the Logical Positivism logical positivists of the Vienna Circle . A simplified form of the theory states that a proposition s meaning is determined by the method through which it is Empiricism empirically verified. In other words, if something cannot be empiricially verified, it is meaningless. For example, the statement It is raining is meaningless unless there is a way whereby one could, in principle, verify whether or not it is in fact raining. The theory has radical consequences for traditional philosophy as it, if correct, would render much of past philosophical work meaningless, for example metaphysics and ethics. It is important to note that the theory is meant to be applied only to synthetic claims i.e. claims about the world , rather than analytical ones. The statement of the theory itself was taken by Ayer to be an analytic claim.

Unreferenced date December 2009 The Address Verification System AVS is a system used to verify the identity of the person claiming to own the credit card . The system will check the billing address of the credit card provided by the user with the address on file at the credit card company. The other security features for the credit card include the Card Security Code CVV2 number. AVS verifies the numeric portions of a cardholder s billing address. For example, if your address is 101 Main Street, Highland, CA 92346, AVS will check 101 and 92346 . Sometimes AVS checks additional digits such as an apartment number, other times it does not. Cardholders may receive false negatives, or partial declines for AVS from Electronic commerce e commerce verification systems, which may require manual overrides, voice authorization, or reprogramming of the AVS entries by the card issuing bank. AVS support At present, only a few countries support AVS on Visa Inc. Visa and MasterCard , notably the USA, Canada and the United Kingdom. American Express does not support AVS in other countries than the USA. Cardholders with a bank that does not support AVS may receive an error from Internet stores due to the lack of data. Besides the Automated verification, some banks do provide merchants with a manual verification system. Usually this is done for foreign credit card accounts as the AVS only works in the same country.
