A few words from the editor

A few words from the editor

If I have seen a little further it is by standing on the shoulders of giants.

- Issac Newton

If you want your views to be known, we now open this monthly review to columnists, bloggersand IP practitioners. Send us an email at [email protected] and lets discuss how we canwork together. We also accept advertorial and advertisement placements.

Structure of this review

The Table of Contents is created based onalphabetical order of IPC. The patent applicationsare also sorted by alphabetical order of IPC. A briefdescription of each IPC is shown. We find that the IPCdescription could help deciphering the abstract of anpatent application. If a patent application belongs tomultiple IPC, the patent application will only be shownunder the section of first IPC.

For each patent application, the following informationwill be shown:

1. App. No. patent application no. it is uniqueto each patent application.

2. Assignee this is owner of the patentapplication. If there is no assignee beingspecified, either the inventor of the patentapplication own the patent application or theowner of the patent application did not recordsuch information when the patent applicationwas filed.

3. Title this is the title of the patent application.

4. Abstract this is the abstract of the patentapplication. There are rules on how an abstractshould be drafted. Most patent attorneys like tohave the abstract based on the first claim of thepatent application.

5. Pri. Date priority date it is the dateof filing of the first application of the patentapplication (a patent application could havemultiple application dates because of divisionalpatents as well as overseas patent applications).It is considered to be the effective date of filingfor the examination of novelty and inventivestep or non-obviousness for the subsequent

application claiming the priority of the firstapplication.

6. App. Date application date it is the date offiling of the patent application at the US.

7. Pub. Date publishing date it is the date of thepatent application published by US. Usually, it isabout 18 months after the application date.

Patent Index is a numerical sorted list the patentapplications appeared in the review.

IPC Catchword Index is an alphabetical sorted list ofcatchwords of the IPC appeared in the review.

App. No. 20100100947 Assignee Apple Inc.Title Scheme for authenticating without password exchange

Abstract Aspects relate to systems and methods implementing a scheme allowing a Verifier (V) toauthenticate a Prover (P). The scheme comprises pre-sharing between V and P a graph of nodes.Each node is associated with a polynomial. V sends P data comprising data for selecting apolynomial of the graph, such as traversal data for proceeding from a known node to anothernode, a time interval, and a number k. P uses the time interval in an evaluation of the polynomial.P then uses the evaluation as a x3bb; in a Poisson distribution, and determines a value related toa probability that a number of occurrences of an event equals k. P sends the determined valueto V. V performs a similar determination to arrive at a comparison value. P authenticates V ifthe separately determined values match, or otherwise meet expectations. The process can berepeated to increase confidence in authentication.

Title Efficient techniques for modifying audio playback rates

Abstract Improved techniques for modifying a playback rate of an audio item (e.g., an audio stream) aredisclosed. As a result, the audio item can be played back faster or slower than normal. Theimproved techniques are resource efficient and well suited for audio items containing speech.The resource efficiency of the improved techniques make them well suited for use with portablemedia devices, such as portable media players.

App. No. 20100098350 Assignee APPLE INC.

Title Blur computation algorithm

Abstract Disclosed herein is an improved blur computation algorithm. The proposed algorithmaccomplishes a blur of an image using fragment programs on a GPU. Alternatively, the blur maybe computed on a CPU through emulation or directly programmed. Modifications of the programare possible that accomplish motion blur, zoom blur, radial blur, and various other forms of blurthat vary across an image computed for the purpose of simulating depth-of-field.

Title System and method for stream/block cipher with internal random states

Abstract Disclosed herein are systems, methods, and computer readable-media for performing dataencryption and decryption using a stream or block cipher with internal random states. The methodincludes splitting the input data into a predetermined number of blocks and processing each block.The processing includes creating sub-blocks, permuting the sub-blocks, replacing bytes using a

lookup table, rotating bits, performing expansion and combining sets of bits. The element ofrandomness employed in this process allows for the same input to yield the same output, withdiffering internal states.

App. No. 20100098255 Assignee Apple Inc.

Title System and method for a derivation function for key per page

Abstract Disclosed herein are systems, methods and computer-readable media to perform data encryptionand decryption using a derivation function to obtain a key per page of data in a white-boxenvironment. The method includes sharing a master key with the sender and receiver, splittingthe input data into blocks and sub-blocks, and utilizing a set of keys and a master key to derivea page key. In another aspect of this disclosure, the key validation and shuffling operations are

included. This method allows for the derivation of a key instead of storing a predetermined key,thus maintaining system security in a white-box environment.
