## Background
BACKGROUND
The present invention generally relates to managing images stored on personal electronic devices, and more particularly to methods and systems for timed deletion of images from personal electronic devices.
The use of smartphones, and other similar personal electronic devices, to take pictures has increased dramatically in recent years. As the quality of the cameras on personal electronic devices improve, the image files that are created by the cameras consume more storage space. Since individuals have their smartphone on hand often, they end up taking more and more photographs, which may result in using a large amount of the storage capacity of their smartphone. Often, photographs are taken by individuals to jot down quick notes that are only useful for a certain period. For example, a user may take a photograph to remind them of where they parked their car, a photograph of a concert or movie ticket which will be redeemed later that night, or a photograph of a document that a friend requests. Such photographs may only be important for a short period of time and afterward the images simply take up storage space.
In general, photographs taken by smartphones, or other similar personal electronic devices, remain on the personal electronic device until the user deletes the photographs, thereby freeing up storage space on the device. Often, people only review and delete unwanted images from their device once the device runs out of storage space. This situation can be frustrating to the user and can result in the user having to review and delete images from their device at an inopportune time.

DETAILED DESCRIPTION
Embodiments include methods, systems, and computer program products for timed deletion of images from personal electronic devices. In exemplary embodiments, when an image is captured by a personal electronic device it is tagged by the user for automatic deletion after a desired time period, which can be specified by the user. Once the desired time period has passed, the personal electronic device can delete the image. In exemplary embodiments, deleting the image can include permanently removing the image from the personal electronic device or moving the image to a deleted items folder.
In exemplary embodiments, the personal electronic device is configured to analyze images stored on the personal electronic device to detect elements in the images that indicate that the image will be unnecessary after a period of time. Once an image is identified having a limited useful life, the image is automatically tagged for deletion. In one embodiment, the tagged images can be moved to a tagged for deletion folder where the user can review these images before the images are deleted from the personal electronic device. During the review of the images in the tagged for deletion folder, the user can revoke the deletion tags and move the images back to another folder.
Referring to FIG. 1, there is shown an embodiment of a processing system 100 for implementing the teachings herein. In this embodiment, the system 100 has one or more central processing units (processors) 101a, 101b, 101c, etc. (collectively or generically referred to as processor(s) 101). In one embodiment, each processor 101 may include a reduced instruction set computer (RISC) microprocessor. Processors 101 are coupled to system memory 114 and various other components via a system bus 113. Read only memory (ROM) 102 is coupled to the system bus 113 and may include a basic input/output system (BIOS), which controls certain basic functions of system 100.
FIG. 1 further depicts an input/output (I/O) adapter 107 and a network adapter 106 coupled to the system bus 113. I/O adapter 107 may be a small computer system interface (SCSI) adapter that communicates with a hard disk 103 and/or tape storage drive 105 or any other similar component. I/O adapter 107, hard disk 103, and tape storage device 105 are collectively referred to herein as mass storage 104. Operating system 120 for execution on the processing system 100 may be stored in mass storage 104. A network adapter 106 interconnects bus 113 with an outside network 116 enabling data processing system 100 to communicate with other such systems. A screen (e.g., a display monitor) 115 is connected to system bus 113 by display adaptor 112, which may include a graphics adapter to improve the performance of graphics intensive applications and a video controller. In one embodiment, adapters 107, 106, and 112 may be connected to one or more I/O busses that are connected to system bus 113 via an intermediate bus bridge (not shown). Suitable I/O buses for connecting peripheral devices such as hard disk controllers, network adapters, and graphics adapters typically include common protocols, such as the Peripheral Component Interconnect (PCI). Additional input/output devices are shown as connected to system bus 113 via user interface adapter 108 and display adapter 112. A keyboard 109, mouse 110, and speaker 111 all interconnected to bus 113 via user interface adapter 108, which may include, for example, a Super I/O chip integrating multiple device adapters into a single integrated circuit.

In exemplary embodiments, the personal electronic device 200 is configured to capture and tag images and/or video for timed deletion. Traditionally, photographs are taken on smartphones using a shutter button located on the touchscreen, or using another part of the user interface 208. In one embodiment, when a user takes a photograph with a personal electronic device 200, the user can tag the photograph for automatic deletion by taking a specific action with the user interface 208 during the taking of the photograph or shortly thereafter. For example, the user interface 208 may include two buttons that can be used to take a photograph, one standard button and one tagged for deletion button. In another example, the user can indicate that the photograph should be tagged for deletion by holding down a specific button of the user interface 208 while taking the photograph (for example, holding down the volume up/down button while pressing the shutter button).
Referring now to FIG. 3, a flowchart illustrating a method 300 for timed deletion of images from a personal electronic device is shown. As shown at block 302, the method 300 includes receiving an image from a camera of the personal electronic device. Next, as shown at block 304, the method 300 includes storing the image in a first location in a memory of the personal electronic device. In exemplary embodiments, the first location may be associated with a photographs folder or images folder on the personal electronic device. The method 300 also includes storing an indication of an expiration time for the image in the memory of the personal electronic device, as shown at block 306. In exemplary embodiments, the indication of an expiration time for the image in the memory of the personal electronic device is generated based on the photograph being captured using a predetermined function of a user interface of the personal electronic device. In exemplary embodiments, the indication may be stored as part of the image file or it may be stored in a separate file. Next, as shown at block 308, the method 300 includes removing the image from the first location in the memory based on a determination that a current time has passed the expiration time.
In exemplary embodiments, after the indication of the expiration time for the image in the memory of the personal electronic device is created and stored, the user is notified so that they can modify or remove the indication if the image is deemed important. In some embodiments, every image that is automatically deleted is sent to a “recently deleted” folder, where they will stay for set time period before being permanently deleted to ensure that no images are inadvertently deleted. In exemplary embodiments, images that have been tagged for automatic deletion are displayed using a visual indicator to convey that they are tagged for automatic deletion.
Referring now to FIG. 4, a flowchart illustrating a method 400 for timed deletion of images from a personal electronic device is shown. As shown at block 402, the method 400 includes receiving an image from a camera of the personal electronic device. Next, as shown at block 404, the method 400 includes storing the image in a first location in a memory of the personal electronic device. In exemplary embodiments, the first location may be associated with a photographs folder or images folder on the personal electronic device. The method 400 also includes creating an indication of am expiration time in response to receiving a request to automatically delete the image after a period of time, as shown at block 406. In exemplary embodiments, the indication of an expiration time for the image in the memory of the personal electronic device is generated based on the photograph being captured using a predetermined function of a user interface of the personal electronic device. Next, as shown at block 408, the method 400 includes storing the indication of the expiration time for the image in the memory of the personal electronic device. In exemplary embodiments, the indication may be stored as part of the image file or it may be stored in a separate file.
The method 400 also includes removing the image from the first location in the memory based on a determination that a current time has passed the expiration time, as shown at block 410. In exemplary embodiments, the personal electronic device includes settings that individuals can us to specify a time period after which images marked for deletion will be deleted. Next, as shown at block 412, the method 400 includes storing the image in a second location in the memory based on a determination that the current time has passed the expiration time
Referring now to FIG. 5, a flowchart illustrating a method 500 for timed deletion of images from a personal electronic device is shown. As shown at block 502, the method 500 includes obtaining an image from a first location in a memory of the personal electronic device. Next, as shown at decision block 504, the method 500 includes determining if the image should be tagged for automatic deletion. In exemplary embodiments, the determination of whether an image should be tagged for automatic deletion can be based on an analysis of the contents of the image. If the image should be tagged for deletion, the method proceeds to block 506 and tags the image for automatic deletion with an expiration time. The expiration time is determined based on one or more settings of the personal electronic device, the date and time that the image was taken and/or the contents of the image. Next, as shown at decision block 508, the method 500 includes removing the image from the first location in the memory based on a determination that a current time has passed the expiration time.
In exemplary embodiments, the contents of an image stored on a personal electronic device can be analyzed to determine if the image should be marked for automatic deletion. In one embodiment, a picture-to-text algorithm can be used to extract the text from an image, and if the image includes dates that have all passed, the image can be tagged for automatic deletion. For example, the image could be tagged for automatic deletion on a date that is thirty days past the last date shown in the image.
In exemplary embodiments, the processor of the personal electronic device can analyze images stored in the memory of the personal electronic device will look for other indications that the image should be tagged for automatic deletion. Such indications can include handwritten notes, which may reflect an unnecessary image like a shopping list. Further, the processor of the personal electronic device can monitor what type of images are being deleted by the user by learning from manual deletes of pictures and learn characteristics of images that are usually deleted. As a result, the processor of the personal electronic device can use predictive analytics to suggest images for deletion in the future (for instance, if the user deletes screen shots frequently, they may be candidates for deletion suggestion).
In exemplary embodiments, by automatically deleting images that are no longer needed, the user of the personal electronic device will no longer need to manually review all of their images and figure out which ones are unnecessary and should be deleted in order to free up storage space on the device.
