Abstract: In an approach, a processor identifies a plurality of text separators in a borderless table, a text separator of the plurality of text separators defining a non-text region between two consecutive text lines in the borderless table. A processor classifies the plurality of text separators into a number of target clusters comprised in a target group based on property information related to the plurality of text separators, the number of target clusters corresponding to a number of separator types. A processor provides indication information to indicate respective separator types of the plurality of text separators based on a result of the classifying.

Abstract: A mechanism is provided for enhancing security access to a data processing system. Responsive to authenticating a first factor of the multi-factor authentication by matching a scanned fingerprint/thumbprint of a user to at least one previously scanned fingerprint/thumbprint in a set of previously scanned fingerprints/thumbprints, a determination is made as to whether a touch pressure level exerted by the user on a touch pressure sensor associated with the data processing system matches at least one previously stored touch pressure level in a set of previously stored touch pressure levels. Responsive to matching the touch pressure level exerted by the user to a previously stored touch pressure level in the set of previously stored touch pressure levels, a second factor of the multi-factor authentication is authenticated. Access is then granted for the user to the data processing system.

Abstract: In an approach, data of a plurality of points is sampled in a target area, wherein the data of each point of the plurality of points comprises position information and a height value. A first area of a target area is determined, wherein the height value of each point of the plurality of points in the first area complies with a first range. A second area of the target area is determined, wherein the height value of each point of the plurality of points in the second area complies with a second range. A third area of the target area is determined, wherein the height value of each point of the plurality of points in the third area complies with a third range. A first pattern is generated, wherein the first pattern is a combination of the first area and the third area.
