An Overview of Apple's Patent

Apple's patent is about a safe deposit box for securing important user files. In one aspect, when a user drags-and-drops a file representation onto a safe deposit box icon, the file is secured. In another aspect, when a user selects the safe deposit box icon and verifies his or her identity, the user could access secured files through a safe deposit box window.

Advantages perceived by this invention include first and foremost that files could be securely stored and that copies of important files could be automatically generated and protected. In addition, file loss could be minimized; confidential information within a file could be protected; users could more easily secure the files that matter the most to them; users could be provided with an interface for protecting valuables that mimics a physical safe deposit box at a bank, a personal safe, or another way of safekeeping valuables. And lastly, the safe deposit box interface could allow access to files for only short periods of time to minimize the risk of an unauthorized user viewing the files.

Two Main Security Dangers

In some implementations, the safe deposit box program takes various actions to further secure the file from one, or both, of two main dangers: someone without authorization accessing the file, and a physical loss of the file due to failure of a storage device storing the file.

To protect against someone without authorization accessing the file, the safe deposit box program can encrypt the file (e.g., using standard encryption techniques), obfuscate the file name (e.g., by renaming the file with an alphanumeric phrase that the safe deposit box associates with the old file name), or take other actions.

In some implementations, the safe deposit box program copies the file to a secure location and deletes or securely deletes the original version of the file. Secure deletion is performed, for example, by overwriting the file with alternating patterns of data that make it difficult to recover the file. An example standard for secure deletion is the U.S. Department of Defense standard 5220.22-M.

To protect against physical loss of the file, the safe deposit box program could make one or more copies of the file and store them in different places in local storage on the user computer or in external or remote storage accessible to the user computer. More specifically, remote storage includes a cloud based solution.

Safe Deposit Box: Using the Cloud for Storage

One of the key attributes or selling points of Apple's Safe Deposit Box Application or OS X feature is that your digital valuables could be stored "off site" or beyond the home computer to safeguard your digital valuables which could be something like a Will or Living Will, agreements, life insurance policies, home insurance policies, a simple home inventory list or video or perhaps something that's really valuable to most every iTunes fan: a copy of your iTunes Library.

In Apple's patent FIG. 4 illustrated below we see an example system 400 showing a user computer coupled to various storage devices. Cutting to the chase, Apple's patent states that "the user computer is also optionally coupled to one or more remote storage devices 412 through a network 414 (e.g., the Internet). The remote storage devices could be, for example, other computers such as a server bank or cloud storage."

Without a doubt, Apple will either include it in Time Machine with OS X Lion or consider it as a separate pro-like app the way that Apple has iPhoto and Aperture for more value. Personally, I think it should be one of the perks for adopting OS X Lion. It's a value proposition and one that will ease everyone, young and old, into trusting "cloud" based services. Then again, Apple may decide to slide this feature into MobileMe so as to push more business its way and expand their cloud services. Time will tell.

Little Notable Features

Apple usually adds little notable features to their apps just to show that they still have a pulse, unlike La Garbage Co. from Redmond. One cute OS X feature relates to removing apps from the dock. When doing so, there's a little puff of smoke action that kicks in so as to notify you that that app has vanished back into your apps folder. That attention to detail is a crowd pleaser with Mac Newbies. 

For the Safe Deposit Box, Apple is thinking of adding "a noise mimicking a creaky door swinging open" when you first open the safe deposit box app and some kind of slamming sound like a deep clunk of a heavy vault door when your finished with the app. They also intend to add a tactile element to this sequence for those with touch based iOS devices. 

The Timeout Monitor Feature

In additon, Apple also talks about something called "the timeout monitor" which determines whether the safe deposit box window should be closed after a certain amount of time. In some implementations, Apple states, "the timeout monitor tracks how long the safe deposit box window has been open and closes it after a preset time (e.g., a time period specified by a user in a preference setting, or a hard-coded period of time). The time could be hardcoded into the timeout monitor or could be changed, for example, in response to a user specifying a desired time for the safe deposit box window to stay open."

Storage Preference Screen

In some implementations, when a user drops the file representation onto the safe deposit box icon as shown above in FIG. 2, the user will be presented with a preferences screen to allow the user to specify various preferences for the file. For example, the preferences screen could allow the user to specify one or more of permissions for the file (e.g., could the file be modified or just viewed, and could the file be transferred or copied from the computer), how many copies of the file should be made, a storage preference policy indicating where copies should be stored, and whether the file should be encrypted. The preference screen could also allow a user to specify an importance level of the file (e.g., according to a rating scale). This importance level could be mapped to other preference values, such as how many copies of the file should be made and whether the file should be encrypted (e.g., important files should be encrypted, and the more important the file is, the more copies should be made).

Safe Deposit Box Manager

Apple's patent FIG. 5 illustrates an example architecture for safe deposit box manager. 

Apple credits Duncan Kerr and David Falkenburg as the inventors of patent application 20110040980, originally filed in Q3 2009.

Another Security Patent was Filed this Week

On the serious side of security, we note that the USPTO published an Apple patent titled "Sponge and Hash Functions using a Rubik's Cube Puzzle Process" under application number 20110040977. Apple's patent states that "the present sponge and hash processes are based on the concept and rules of physical Rubik's cube puzzles. The Rubik's cube is a well known three dimensional mechanical puzzle invented by Erno Rubik. It's a cube (so having 6 faces). The sides of the cube are colored. There are 26 miniature cubes that make up the main cube, called cubies or cubelets. A pivot mechanism allows each face of the cube to turn independently to mix up the colors. Each face has 9 sub-faces, arranged 3.times.3 in terms of the cubies. The standard Rubik's cube has 4.33.times.10.sup.19 permutations, so the puzzle is capable of achieving a high degree of randomness. Solving the conventional puzzle requires arranging it so each cube face is all one color."
