Phidden vs HideNSee Secure Message&Photo

Welcome to Phidden! Hide your message in your photo. With this new App you will be able to send your secret messages to your friends and let others believe that you have only sent them a photo! All you have to do is choose your best photo, write your message and Phidden does the rest! It will hide your message within the photo and all you need to do is share ! Whoever receives it will be able to read the message contained only by opening it with Phidden and with no other App or program! ATTENTION The messages hidden in Phidden can only be ‘decoded’ with the same App! For the same reason every photo not ‘encoded’ by Phidden if ‘decoded’ by the same App will return a blank and incomprehensible message! This is not to be considered an error but a non-coded photo! COMPRESSION IS THE ENEMY OF PHIDDEN! ANY FORM OF COMPRESSION WILL COMPROMISE THE HIDDEN MESSAGE! Many file sharing, e-mail client, social network and sharing services usually have a habit of compressing images, so do not entrust them with your encoded photos if you don’t want to lose the hidden message! For the same reason photos should be attached and sent in the original dimensions, as any form of compression will compromise the message and will make it illegible and not decodable! The safest way to maintain the integrity of the secret message is to post the image on Phidden Network ! Other secure methods remain saved in the library, AirDrop, messages or emails (only if sent at maximum resolution). Feel free to make personal tests with the services you usually use to verify if the message remains decodable. NOTE: the use of Phidden, the content of the hidden messages in the photos and their disclosure is to be considered the free choice of the user, the developer cannot be held in any way responsible. Don't forget to leave a review! Your feedback is precious! Thanks for your support ACKNOWLEDGMENTS A warm embrace and particular thanks goes to my friends @Alessio_Vinerbi and @lkaroweb for their help with the code that drives the engine of the App! Heartfelt thanks, guys! Photo and background image by unsplash.com

- Unencrypted text and photo transmission may be viewed by unwanted third parties. Send and receive secure messages and photos directly with people you trust. - We do not operate any servers to run this app. Messages you send and receive with people you trust using this app are delivered using your phone's SMS, Email, or other messengers. (We think using SMS will provide a bit more security. .) - This app provides users with a very high-level security message by optimally combining the high-security key manager provided by the mobile phone and encryption algorithms of RSA, AES, and SHA2. - Texts and photos using this app can be safely viewed at the moment you need them only by the owner of the phone and remembering the password. Check if the messenger you are using is safe. 1. How does the messenger you are using protect your messages from third parties? - Your unencrypted messages are leaked very easily. - If the encryption method does not use the latest technologies, the message cannot be said to be secure. 2. Can you trust the messenger service provider you are using? - Your message may exist on the service provider's server for a certain period of time. - Even reliable service providers are sometimes unable to protect your messages from public authorities or hackers. 3. Isn't it easy for the person behind you to see the chat screen via messenger? - Most IM screens are difficult to protect because anyone with a clear line of sight can see them. 4. If I lose my phone, are the messages in it safe? - Unencrypted or low-level encrypted messages can be viewed by professional hackers. #Very important To send and receive HideNSee secure messages, you must use this app to create a safe chat room in the following order. 1. Invite a contact from your contacts in this app. The invitation message is sent as one SMS text and one MMS file. - The invitation message contains my 'public key' that does not matter if a third party takes it. - Since the 'public key' is used to encrypt the message and only the user with the 'private key' can see the encrypted message, it does not matter if a third party takes the 'public key'. 2. The invitees share the received MMS file with the HideNSee app. - The received MMS file is saved in My App as the 'public key' of the inviter. 3. The invitee sends his/her 'public key and symmetric key' as an MMS file to the invitee. - Since the 'Symmetric Key' is encrypted with the 'Public Key' of the inviter received earlier, it is safe from hacking. - It is handled automatically by the HideNSee app, and the user only confirms the selection and use of the MMS file sending app. 4. The inviter shares the received MMS file (the other party's 'public key and symmetric key') with the HideNSee app. - The received 'public key and symmetric key' is stored in the app. 5. A secure chat room has been created. - Two people encrypt and store the inviter's 'Symmetric Key' with their 'Public Key', and use their 'Private Key' to unlock and use only the moment they send a message to the other. - If your phone is not in use by jailbreaking, your 'private key' is stored in the most secure device of your phone and is safe. - Even if someone steals the 'private key', it is virtually impossible to use the 'private key' unless you know the password you remembered when installing the app. 6. The symmetric key is stored securely in both people's apps and no one can see the messages you send to each other. Send and receive messages securely using the HideNSee app. The HideNSee app also provides a way to protect against message hijacking by deleting all stored messages in a way that others do not know, even when you are forced to launch the app and show your messages.
