The present invention generally relates to the field of automated and flexible information extraction and protection for graphical data. In particular, the novel present invention provides a unique platform for analyzing, classifying, extracting, and processing information from images using deep learning image detection models. Embodiments of the inventions are configured to provide an end to end automated solution for intelligently hiding or obscuring private data from graphical displays via the use of embedded steganographic image data techniques.
Current tools for data extraction from images which provide an end to end automated solution for extraction and classification of data in consistent useable format are valuable tools for processing graphical information. Seeing as deep learning image detection models involve tremendous effort and resources to train and perfect, preserving the integrity of such models and controlling the distribution of such models is important. In many current processes, techniques and systems, a user is required to manually select graphical attributes and calibrate axis metrics for proper data extraction. As such, these processes are time consuming, prone to human error, and result in data that is not uniform. The output data produced by such conventional solutions are often minimally useful and have a potential for producing unintended effects or unhelpful data analysis when unattended by comprehensive human review.
In terms of conventional solutions for graphical display security, most currently available solutions and devices have to be manually and physically installed as a means of privacy screen protection. For instance, a privacy screen protection sheet may be placed over a user interface display or monitor to obscure displayed information from being viewed at certain angles, distances, or the like. If a user is using a personal device, they may be exposed to security issues in public environments, and may resort to constant diligence in manually obscuring their screen from unauthorized or unintended view. Conventional physical privacy screen protection solutions also include inherent drawbacks; the screen brightness is reduced, and the presentation may be bulky or detract from the overall aesthetic of the device itself. To counter these drawbacks, device brightness typically needs to be increased, leading to higher power consumption, shorter battery cycle life, and decreased battery longevity as a result of more frequent recharging. A dynamic, digital solution is preferable.
The previous discussion of the background to the invention is provided for illustrative purposes only and is not an acknowledgement or admission that any of the material referred to is or was part of the common general knowledge as at the priority date of the application.
The following presents a simplified summary of one or more embodiments of the invention in order to provide a basic understanding of such embodiments. This summary is not an extensive overview of all contemplated embodiments, and is intended to neither identify key or critical elements of all embodiments, nor delineate the scope of any or all embodiments. Its sole purpose is to present some concepts of one or more embodiments in a simplified form as a prelude to the more detailed description that is presented later.
Embodiments of the present invention comprise systems, methods, and computer program products that address these and/or other needs by providing an innovative system, method and computer program product for intelligent obfuscation of graphical data to provide enhanced privacy of a user device display. In particular, the present invention solves the need for a dynamic digital solution for providing screen privacy through the use of a situationally aware system for selectively applying random image data to a user display screen through the use of a steganographic function based process. As such, the invention provides an intelligent solution at times where sensitive or confidential information may be displayed on-screen and the user device may be within public view.
The system gathers various user data from user devices in order to dynamically determine a level of visibility appropriate given each unique setting, and may also base this determination on specific user preferences or movement patterns. For instance, the system may receive data indicating that a user device is currently connected to a public network or is geolocated at a public area, and may implement a digital screen protection process for obscuring sensitive or confidential information in this instance. In addition, the system may receive data to indicate the orientation of the screen, the user's position relative to the screen, or the like, in order to selectively obfuscate data from being viewed at only certain angles, while retaining visibility from solely the user's determined perspective.
The invention is an ideal solution for users who are flying, commuting, working in a cafe or other public space. Via the use of the system, the user's screen can be protected, and privacy may be provided, as the content displayed on-screen will be visible only from certain customizable viewing angles. Furthermore, at a private location, like the user's home, car, or the like, the user device may be given an option to enable all viewing angles, and the system may log user information received from the user device in these instances in order to create a datastore of trusted scenarios, and locations. In some embodiments, automatic viewing angle restriction can be selected based on location, time, or the like, according the user's set schedule, or according to an inferred pattern or schedule that becomes evident over time according to gathered user data. In preferred embodiments, the implementation of the invention solution will not impact screen brightness when viewing from best viewing angles, thus alleviating the issue of increased power consumption or decreased battery life of conventional display privacy solutions, such as polarized physical screen coverings or shields.
Typically the system comprises: at least one memory device with computer-readable program code stored thereon; at least one communication device; at least one processing device operatively coupled to the at least one memory device and the at least one communication device, wherein executing the computer-readable code is configured to cause the at least one processing device to: receive an original image for analysis from a user device, wherein the original image comprises an image displayed on a graphical user interface of the user device; encode the original image using multiple convolutional neural network layers; embed, simultaneously, a steganographic layer containing randomized portions of a secret image into the encoded image such that the randomized portions of the secret image obscure portions of the original image; and encrypt and store pooling indices for the randomized portions of the secret image in encoding feature variance layers of the encoded image.
In some embodiments, the system is further configured to: apply a stegoanalyser to the encoded image to remove the steganographic layer resulting in a processed encoded image; and decode the processed encoded image using additional multiple convolutional neural network layers to identify and extract feature data.
In some embodiments, the multiple convolutional neural network layers further comprise batch normalization to normalize a scale of the encoded image and reduce internal covariance shift between the multiple convolutional neural network layers.
In some embodiments, the multiple convolutional neural network layers further comprise using one or more linear-activation functions.
In some embodiments, embedding the steganographic layer containing randomized portions of the secret image further comprises applying multiple hidden convolutional layers during encoding and wherein the hidden layers are applied between at least two separate convolutional neural network layers.
In some embodiments, the system is further configured to: receive geolocation data from the user device or one or more auxiliary user devices; based on the geolocation data, determine that the user device is in a public location; and determine portions of the original image to obscure based on the user device being in a public location.
In some embodiments, the system is further configured to: store user-specific location or time preferences, wherein the user-specific location or time preferences comprise specific locations or times wherein the user prefers the system to activate; and continuously monitor geolocation data received from the user device or one or more auxiliary devices.

As shown at block 205, the process begins when the system receives an original image for analysis, referred to in
Next, the process proceeds wherein the system encodes the original image 301 using multiple convolutional neural network layers, as shown by block 210, and as further described in
The system may then identify and extract data series and contours from the image, wherein the data series and contours and partially identified based on relative and proportional data determined by the object mask layer. In some embodiments, the recognition of data series from contours may be achieved by use of a combination of regression analysis, text mining, and classification analysis. This data may be organized and stored in data repository 160 such that it can be easily incorporated into a detailed dashboard of image features. The process may apply an optical character recognition process to transform any identified text data into a searchable format, and generates a segmented image. Segmented information and identified text data is compiled and stored in the data repository 160 for incorporation in a selective output of masked or unmasked image features. The processed image may be compared to the original image 301 to validate that the resulting segmented image maintains an accurate overall depiction, or a depiction which retains viewability from one or more specific angles of view.
As shown in block 215, the system simultaneously embeds a steganographic layer containing randomized portions of a secret image into the encoded image such that the selected randomized portions of the secret image are undetectable, yet visibly apparent as obfuscation, as further described in
The process proceeds to block 220 where a stegoanalyser, such as stegoanalyser 158, is applied to the encoded image to remove the steganographic layer, resulting in a processed encoded image that can be effectively fed to the decoder network architecture for decoding and feature detection. Finally, the process proceeds to the decoding step wherein the processed encoded image is decoded using multiple additional convolutional neural network layers to identify and extract features data.
The features identified by the model may vary based on the application of the CNN model 156. For instance, the model may be trained to detect boundaries within the original image 301 that correspond to charts, graphs, tables, or images of any number of objects or object characteristics. Shown in
The insertion of additional image data containing portions of secret images is represented in
As shown, the model receives an original image 301 for processing at the convolutional encoder 310. The original image 301 is encoded and convoluted using a number of convolutional layers, as further described in
The insertion of additional image data containing portions of secret images is represented by secret image 302. As shown, the steganographic function 303 that exists within the convolutional encoder 310 incorporates image data from the secret image 302 into encoded image which results in an embedded secret image 304. However, as shown in
As shown in the particular embodiment represented in
As the filters are applied to the image, each encoder convolution layer 512 contains a pooling step where the dimension of the encoded image is reduced to highlight only critical information. Data about how the encoded images are reduced is stored as a pooling index. These pooling indices are carried over into the decoding network and the decoding network applies additional convolution layers which expand the pooling indices to predict the original image 301. In some embodiments, the CNN model 156 may use a min or max pooling method, while in other embodiments the CNN model 156 may use an average pooling method. Each encoder convolution layer 512 may also contains a batch normalization step which scales the encoded image data to a normalized scale. Applying batch normalization at encoder convolution layers effectively reduces internal covariance shift and aids in reaching convergence of the decoded image as compared to the original image 301 by giving the CNN model 156 more generic decision functions. The filters used in the CNN model 156 are trained over time using a feedback process of encoding and decoding in order to achieve a resultant model which can identify a specific feature set. The data within the matrices of the filters is weighted to identify specific features based on training data.
Returning to the exemplary embodiment used in
Also depicted in
As discussed in
As with the encoder network architecture 510, each of the decoder convolution layers 532 also contains a batch normalization step which scales the encoded image data to a normalized scale. Applying batch normalization at convolution layers effectively reduces internal covariance shift and aids in reaching convergence of the decoded image as compared to the original image 301 by giving the CNN model 156 more generic decision functions. In addition, each decoder convolution layer 532 contains a non-linear activation function which is applied in each stegoanalyser convolution layer 522 in order to account for non-linearity of feature distribution within the processed image. The result of decoder network architecture 530 is decoder output layer 533 depicted at output layer on the decoder network architecture 530 which contains a set of mapped features on the resulting image which matches the dimensional and pixel characteristics of the original image 301.
For instance, in some embodiments, the user device 104 may transmit location data to the system 108, which the system may cross reference with publicly available data or previously stored data in the data repository 160 in order to determine that the user device 104 is in a public location (e.g., an airport, cafe, or the like). In other embodiments, the user device 104 may transmit data indicating a state of operation, such as current network connectivity data, an IP address, or the like, which may allow the system to determine the location of the user device 104. In still further embodiments the user device 104 may be communicating with the system 108 via one or more auxiliary user devices 605, such as a public WiFi network, or the like, which may be indicated by the incoming packets of the data stream between user device 104 and system 108 (e.g., the geolocation of a public WiFi network address may be known prior by the system 108, and the incoming data stream may indicate that the user is transmitting information over the public WiFi network, therefore evidencing that the user is in a public location, or the like). In still further embodiments, auxiliary user devices 605 may be in separate communication with the system 108, and in these instances, the system 108 may correlate or cross-reference data received directly from the user device 104 and the auxiliary user devices 605 in order to determine that the devices are in proximity to one another (e.g., the geolocation of a public WiFi network address may be known prior by the system 108, and cross referenced with geolocation data of the user device to determine that the user is in a public location, or the like).
The system 108 receives data from scenario 601 and intelligently correlates this data to identify user pattern behavior and preferences using machine learning vulnerability detection model 610. For instance, in some instances, the user 102 may manually enable the intelligent display protection system 108, and the system may annotate received data from the user device 104 and auxiliary user devices 605 at that same time in order to note that that the user prefers privacy and screen protection in a given scenario. In some embodiments, the system may store user configuration data unique to each user which contains specific preferences for which locations to activate screen protection. In other embodiments, the activation of screen protection may be based on a set time-based schedule that the user programs. In further embodiments, the system may learn over time that specific days, times, location, or that certain a combinations of any of these specific factors constitute scenarios where the user prefers screen protection to be activated. Over time, the machine learning vulnerability detection model 610 may receive additional data from one or more users 102 and use this data as training data for the steganographic training platform 615. As shown, convolutional neural network model validation 620 may be achieved via communication with the user device 104 to confirm that the intelligently obfuscated output and determined scenarios requiring privacy protection are preferable or acceptable to the user 102.
