Accountability

1. The quality of being responsible, answerable; the obligation to report, explain, or justify an event or situation.

Archival Value

1. "The values, evidential and/or informational that justify the continuing retention of records as archives." (l)

Archiving

1. "the process of creating a backup copy of computer files, especially for long-term storage." (i)

Asymmetric Encryption

1. "A form of cryptosystem in which encryption and decryption are performed using two different keys, one of which is referred to as the public key and one of which is referred to as the private key. Also known as public-key encryption." (a)

Audit Trail

1. "A record showing who has accessed a computer system and what operations he or she has performed during a given period of time." (b)

Authentication

1. "A process used to verify the integrity of transmitted data, especially a message." (a)

2. "The process of identifying an individual, usually based on a username and password. In security systems, authentication is distinct from authorization, which is the process of giving individuals access to system objects based on their identity. Authentication merely ensures that the individual is who he or she claims to be, but says nothing about the access rights of the individual." (b)

3. "the process of confirming an asserted identity with a specified, or understood, level of confidence. The mechanism can be based on something the user knows, such as a password, something the user possesses, such as a ‘smart card,’ something intrinsic to the person, such as a fingerprint, or a combination of two or more of these." (h)

Authenticity

1. Authenticity is a function of a record's preservation and is a measure of a record's reliability over time.

Back-up

1. "To copy files to a second medium . . . as a precaution in case the first medium fails." (b)

Backup

1. "A substitute or alternative. The term backup usually refers to a disk or tape that contains a copy of data." (b)

Biometric-based Device

1. An authentication technique relying on measurable physical characteristics of the user that can be automatically checked. An example is a fingerprint scanner. (b)

Data

1. "Symbols, or representations, of facts or ideas that can be communicated, interpreted, or processed by manual or automated means." (i)

Data Warehouse

1. A computer-based information system that is home for "secondhand" data that originated from either another application or from an external system or source. A data warehouse is a read-only, integrated database designed to answer comparative and "what if" questions. Unlike operational databases that are set up to handle transactions and that are kept up to date as of the last transaction, a data warehouse is analytical, subject-oriented and structured to aggregate transactions as a snapshot in time.

Data Model

1. A diagram that shows the various subjects about which information is stored, and the relationships between those subjects.

DIG-IT

1. Data Issues Group for Information Technology. A Minnesota state government group formed in 1997 as a subcommittee of the Information Policy Council (IPC). Comprised of staff from state agencies and related organizations with an interest in data administration, data modeling, and database administration, DIG-IT's goal was promoting the importance of data as a vital state asset requiring management of its creation, use, storage, dissemination, documentation, and disposition by sharing collective experiences and expertise. DIG-IT ceased meeting in 2003.

Digital

1. "Describes any system based on discontinuous data or events. Computers are digital machines because at their most basic level they can distinguish between just two values, 0 and 1, or off and on. There is no simple way to represent all the values in between, such as 0.25. All data that a computer processes must be encoded digitally, as a series of zeroes and ones." (b)

Digital Signature

1. "An authentication mechanism that enables the creator of a message to attach a code that acts as a signature. The signature guarantees the source and integrity of the message." (a)

2. "In Minnesota, a digital signature is defined to be an asymmetric cryptosystem. . . . A digital signature is a reliable electronic method of signing electronic documents that provides the recipient with a way to verify the sender, determine that the content of the document has not been altered since it was signed, and prevent the sender from repudiating that fact that he or she signed and sent the electronic document. A digital signature is made up of a key pair consisting of a private key and a public key. . . . A signature looks like a random series of numbers and alphabetical characters. Each signature is unique because it uses the content of the electronic document to create the character string." (c)

Disaster

1. "An unexpected occurrence inflicting widespread destruction and distress and having long-term adverse effects on agency operations. Each agency defines what a long-term adverse effect is in relation to its most critical program." (i)

Documentation

1. "The act or process of substantiating by recording actions and/or decisions." (i)

2. "Records required to plan, develop, operate, maintain, and use electronic records. Included are systems specifications, file specifications, codebooks, file layouts, user guides, and output specifications." (i)

Dynamic

1. "Refers to actions that take place at the moment they are needed rather than in advance." (b)

2. "Recorded information that is recorded in a form that requires a computer or other machine to process it. Includes word processing documents; electronic mail messages; . . . Internet and intranet postings; numerical and textual spreadsheets and databases; electronic files; optical images; software; and information systems." (i)

Firewall

1. "A system designed to prevent unauthorized access to or from a private network. Firewalls can be implemented in both hardware and software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria." (b)

Format

1. "The shape, size, style, and general makeup of a particular record." (i)


A  B  C  D  E  F  G  H  I  J  K  L  M  N  O  P  Q  R  S  T  U  V  W  X  Y  Z
