1.3 Definitions
approval indicator: any symbol adopted by the designactivity to indicate approval.associafed documents: general reference to documentationsupportive of and directly related to drawing contentsuch as Parts Lists, Data Lists, Index Lists, Wiring Lists,and Application Lists (see ASME Y14.35M)
authenfication: the process of verifying the claimed identity of a documents author and approver(s).biometrics: the use of biological properties to identifyindividuals, e.g., finger prints, a retina scan, voice recognition, etc.
cryptographic key: a string of bits used widely in cryptography, to encrypt and decrypt data.
digital signafure: a person’s signature transmitted in acoded form (from a computer) by discrete signal ele-ments such that the identity of the signatory and integrity of the data can be verified.
drating: an engineering document or digital data file(s)that discloses (directly or by reference), by means of graphic or textural presentations, or by combinations of both, the physical or functional requirements of an item (see ACME Y14.100). signature: one’s name as written by oneself.
2 REQUIREMENTS Digital approval systems shall provide for the admin- istration and digital application of unique approval indi- cators. These systems shall be amenable to human and machine-readable protocols, provide for accurate data entry, and provide for accountability and traceability.
2.1 Approval Indicator An approval indicator, as used in this Standard, is a symbol of personal identification with the same author- ity as a manually applied signature. It shall be unique, verifiable, applicable to, controlled and applied by an individual, and affixed or hyperlinked to the approved data.
2.1.1 Composition of an Approval Indicator. Approval indicators may consist of any symbol(s), letter(s), num- ber(s); grouping or combinations of symbol(s), letter(s), number(s); or a digital signature. Standard and com- monly used machine-readable markings (e.g., 2D bar code, matrix code, etc.) may be used as approval indi- cators. Trademarks, company logos, etc., shall not be used alone as an approval indicator. However, when com- bined with the approval indicator, such symbols provide clear association with a specific organization or function.
2.1.2 Approval indicators for Engineering Data. A mechanism shall be established and maintained to verify and associate approval indicators to an individual. Uni- formity of approval indicator placement should be estab- lished by company procedures, standards, or policies to enhance visibility and reduce searching.
