The Signature type attribute provides a means of electronically signing an item. The signing attaches a block of identification data to the item that you sign.

Prerequisites

• Digital signing requires the signing user to be logged into a Windows session using a User ID that matches the Network ID in an activated SystemWeaver account
• Items must have a Status of "CS Released" to be digitally signed using this attribute type

Users are provided with an attribute editor to perform the signing when the item(s) are in status "CS Released":

The preview editor shows the display name of the user that signed as well as the date:

Users can also view digital signature information in the pop-up editor: 

When creating an attribute of type Signature, the only requirements are a SID and a Name. 

Valid Data Dimension(s): Single

Support for Default Value: No

Allows Empty Value: Yes

Configurable Editor: Yes, width, but not height

Things to Consider

• Once a Signature attribute is added to an item and is used to sign, the attribute can never be removed from the item.
• A signed item can never be removed. 
• Since you cannot remove the item, and it has a status of "CS Released", this item and any referenced items, including previous versions can never be removed. 
• You can also sign issues, however, the meaning of signing an issue is determined by the workflow definition.
