Abstract: A smartphone that is suitable to shoot or take a video or a photo and save them in an external storage device that can communicate with a connecting unit in the smartphone. The smartphone is capable of being operated in external save mode and to save the video or the photo solely in the external storage device. The smartphone may include an encryption subsystem to encrypt the video or the photo or a voice recordation, and a decryption subsystem. The encryption subsystem can encrypt the video or the photo or the voice recordation in such a way that they can be decrypted by using personal keys that were identified by a personal key identification reader of the smartphone before the camera shoots the video or takes the photo or before the microphone executes the voice recordation.

Abstract: A device for documenting and encrypting a face to face personal meeting that includes a casing, a connecting unit that can communicate with external data storage device, a camera or microphone, an encryption subsystem, a decryption subsystem, and a personal key reader that is capable to identify personal keys of participants of the meeting. The device can encrypt the video that can be decrypted by using the personal keys of the participants. The device can save the encrypted video only in external storage device that communicates with the connecting unit while the camera shoots the video, and it is saved with information of the participants' identified personal keys. The decryption subsystem can decrypt the encrypted video when external storage device in which the encrypted video is saved communicates with the connecting unit and when the reader identifies the identified personal keys of the participants.

Abstract: A method for managing privacy of videos and photos recorded through a communication application by displaying a secret recording button on touch screens of a user's and contact's mobile devices, recording a video or a photo by the user's mobile device, applying on the recorded video or photo a re-watch mode by using the secret recording button, displaying in the message box of the user and the contact the recorded video or photo. The re-watch mode causes the mobile device to transmit the recorded video or photo to be saved in the server, displaying on the touch screens of the mobile devices a re-watch button, sending to the server a re-watch command by using the re-watch button in both mobile devices, receiving from the server the recorded video or photo to the mobile devices, and posting it in the message box of the user and the contact.

Abstract: A method for operating a web platform for selling a product that is performed by processing devices running on computing devices and a server that enables a user to advertise the product for sale and indicate a deadline for submitting purchase offers, enables the user to specify a minimum bid, receives from the user an undertaking to sell the product to a person who will offer at least the minimum bid, saves the minimum bid price in a memory means in the server, enables bidders to submit purchase offers, saves these offers, and on the deadline or after selects the submitted purchase offer with the highest price, and calculates a final price at which that bidder will purchase the product according to a mathematical formula in such a way that the calculated final price is between the minimum bid price and the highest price.

Abstract: A method for managing text messages of a chat between a user and a contact of an instant messaging application that provides the option to apply a secret chat mode on the messages that are written or recorded and displayed in the dialog boxes after applying the secret mode. The method indicates on the screens of the computing devices of the user and the contact that the chat is under the secret chat mode. The method deletes from the dialog boxes the text messages that are under the secret chat mode upon receiving a deleting command from the user or the contact. The deleting command may be automatically created when the user or the contact leaves the chat. The method stores these text messages and re-posts them upon receiving a mutual re-posting command from both the user and the contact.

Abstract: A method for protecting privacy of shared video files that is performed by processing devices running on mobile devices of a first user and a second user and a remote server that enables the users to create a virtual group with a shared dialog box, to store solely on the remote server files of video films that the first user shoots by his mobile device, to display on the shared dialog box links to these files, to enable the second user to select for viewing these links, to stream and playing the video films on the screen of the mobile device of the second user, to prevent the ability of the mobile device to make a screenshot when playing the videos, to prevent abilities of the mobile device of the second user to save, to share or to forward these files.
