Synchronous random number generators PRNG

Let's look at several ways to create software random number generators using external digital streams and without them. Let's write source code for Android Java - prototypes of applications showing the reality of using algorithms.

Generator of "random" numbers using expansion of source information, sampling and correction of source data. (Czech Entropy Application)

We will use TTS technology in this generator - converting the entered text into speech. This option is available in the Android operating system. TTS allows you to significantly increase the volume of data (30-100 thousand times), use different settings to obtain different digital results, ensure repeatability of the results (which makes it possible to build a PRNG), the transformation is “formulaless”. The disadvantages of the algorithm are obvious: the result is easily repeated (if you know the source text), large but not infinite expansion of the data, unstable level of entropy in the obtained data. Because the received data is a sound file, it may contain many repeating and dependent sequences of numbers.
Let's consider possible options for compensating for the shortcomings of such random number generators.
You can come up with (invent) quite a few algorithms for improving the results of such data expanders.
TTS conversion of the entered text several times with different parameters: sound quality, pronunciation speed, male/female voice, timbre, etc. With subsequent mixing of data from several sound files. The complexity of mixing algorithms directly affects the result. For example, you can "reverse" data in one or more audio files before mixing, introduce data shifts, block permutations, etc. At the same time, the repeatability of the results and the possibility of constructing synchronous generators of “random” numbers are preserved.

  Photo Registrar      The site oflameron.com hosts a repository in which the source codes of the application OFLAMERON Rescue Photo will be published. Any Java programmer can analyze Java code and suggest ways to improve it. If the proposed code is added to the application OFLAMERON Rescue Photo , then the author of the code fragment can be indicated in the Copyright.        Interesting suggestions include saving settings to a webserver, downloading new settings from a webserver, managing settings via SMS messages, creating applications for other versions of the Android OS, using a microphone for activation, etc.        These proposals are connected with the author's decision to start work on new programs for control, surveillance, security, protection, alibi provision, etc.         Application OFLAMERON Rescue Photo fully performs all the functions for which it was created by the author. The disadvantages of the program are known: the application setting is not intended for

Czech Entropy

  Android APP Beta version of the application. It is necessary to enter the text in English without punctuation marks longer than 100 characters and press the "GENERATE" button. After a while, a set of "random" numbers will be shown as INTEGERS and HEX. They can be copied to the clipboard for use, for example, in XOR encryption. The length of the set of numbers is 60 bytes. The given text is converted into a set of numbers using formulaless technology and is not reversed. So far, the minimally working algorithm has been used. If the sender and receiver select and enter the same text (for example, the same news item published on CNN at 12 o'clock), they will receive the same set of "random" numbers. Attention. The application DOES NOT encrypt data. The application only generates a synchronous set of numbers. It can be seen that while the quality of the set of numbers is not high. Algorithms for choosing "random" numbers can be significa

Android Java Open Source

Open Source GNU GPL I will publish here ready-made full Java projects for Android devices. The projects will include all libraries and comments and will be completely ready to be compiled into a working application. Projects do not have the most perfect Java code. But they work and you can use it like OIpen Source GNU GPL license   You can upgrade the source code, add features, put your own copyright and even sell the program. Just give my copyright to the source code as well.   Full Open Source Project Photo REGISTRAR - https://drive.google.com/file/d/1hAeNqKd-3nXiMhk_t41p4bXXOuE3kcWH/view?usp=sharing Open Source GNU GPL   When testing a program in Android Studio, you must select the debugging mode on a real smartphone
