Examples relate to providing throttled data memory access. In some examples, a locking mechanism is used to activate a corresponding memory lock after receiving a first read access cycle. While the corresponding memory lock is active, responses to subsequent read access cycles are prevented. After the corresponding memory lock deactivates, a second read access cycle is responded to with access to the memory.

Throttled data memory access

A variable guilloche includes at least two guilloche curves, printed in a common space and having at least one point of overlap. The at least two curves are plotted from equations having variables corresponding to a specified data string of steganographic information.

Variable guilloche and method

A method of extracting a section of a page from a portable document format file (&ldquo;pdf&rdquo;): The method includes receiving indication of a user-defined region on a pdf file page, designating an extraction region including all elements determined to be within the user-defined region, and placing the extraction region into a new file. The method may also include determining if one or more elements on the pdf page are within the user-defined region by applying inclusion rules based on whether an element's bounding box is within or intersects the user-defined region. The method may also include verifying the accuracy of the extraction by converting the user-defined region in the original pdf document and the extracted region to bitmap images and comparing the two bitmap images, bit by bit.
