1. A method for controlling access to an access-protected unit, the method comprising:
- reading a sequence of locations from an encoded base;
checking if the read locations are within a region belonging to an authorized user;
checking if the sequence of locations corresponds to a previously registered signature of the authorized user; and
granting access by the authorized user to the access-protected unit if the location is within the region belonging to the authorized user and the sequence of locations corresponds to the previously registered signature of the authorized user, otherwise denying access, wherein reading said sequence of locations from the encoded base includes recording a pattern from the base with an optically imaging pen, and converting the recorded pattern into locations.

Abstract
A system and method are disclosed for controlling access to an access-protected unit. A location may be read from a base, such as form, using a digital pen. The system may then check if location is within a region belonging to an authorized user. If so, access may be granted to the authorized user to the access-protected unit or to specific programs or functions of the access-protected unit.

8. A system for controlling a user'"'"'s access to an access-protected unit, comprising:
-
a sensing device for reading a sequence of absolute locations which described movement of the sensing device when the user is writing with the sensing device; and a checking device which; determines whether the read locations are associated with at least one region belonging to an authorized user; compares the sequence of locations with a previously registered signature of the authorized user; and
;provides an enabling signal when the checking device determines that access is authorized. - View Dependent Claims (9, 10, 11, 12)

13. A base for controlling access to an access-protected unit comprising:
-
a substrate; a writing field associated with the substrate; and a position coding pattern associated with the writing field, wherein the position coding pattern encodes a plurality of absolute locations used to grant access authorization, whereby the position coding pattern is read during movement of a sensing device over the writing field, and wherein the sensing device is configured to convert the position coding pattern to a sequence of locations during movement of the sensing device, and further wherein the sequence of locations are compared to a previously registered signature of the authorized user for granting access authorization.
