Deniable Encryption is like tit for tat. Let us as assume, you want to decipher an encrypted file of your enemy. If an encrypted file gives you wrong information, you are likely to miss it. The required effort to find the correct file will consume too much time. Deniable encryption is a type of encryption that allows to convincingly deny that usable data is encrypted or keeps no way to be able to … [Read more...]

How to Create Custom Parts for Fritzing
Fritzing is an underappreciated Free Software with own standard. Few parts are sometime missing or you simply need to create your own part or board. Fritzing breadboard view can be made far superior looking than the default look provides. Commonly peoples open some file in Fritzing, or "draw" the circuit and simply forget about it. Tinkercad looks great because the parts are nicely designed. … [Read more...]
Connecting ESP32 Arduino with DHT11 with IBM Watson IoT
Earlier, we described how to create graph on IBM Watson IoT dashboard by using the default widgets. In previous guide, we described how to use ESP32 Arduino with DHT11 sensor. Here is the Code and Diagram to Connect ESP32 Arduino with DHT11 with IBM Watson IoT and Get Odometer Like Gauges on Dashboard. For this guide, you will need : Reading the above linked guides for setup and materials … [Read more...]
ESP32 Arduino with DHT11 Sensor : Connection & Code
Here is Connection & Working Code for ESP32 Arduino with DHT11 Sensor. We will use Adafruit's libraries for DHT11 and DH22 Temperature Humidity Modules. For using DHT11, DHT21, DHT22 with non-ESP32 Arduino please read our previous guide on Arduino Temperature Humidity Sensor. For ESP32, it is mandatory to have the common required setup for Arduino IDE (ESP32 does not work with Arduino IDE out of … [Read more...]
What is Smart City?
The term smart city is an emerging concept, and therefore its meanings is subject to constant revision. It is also a term, which is being used as a marketing concept in the business field, in relation to development policies, and in relation to various specialties and topics. Smart city sometimes also called efficient city or super efficient city, and refers to a type of urban development based … [Read more...]
Which One is Preferred to Make a Smart Doorbell – Raspberry Pi or ESP32 Arduino?
Ideal answer is none. If our previous publication on Watson Visual Recognition with cURL beside guides like sending Push Notification via Watson IoT giving hope of ultra-modern DIY project, then such hope must be killed. We will not supply ideas, projects which will fail with time. Smart Doorbell if used for security purpose demands a commercial solution. DIY solutions mostly for fun at … [Read more...]
Wearables and Internet of Things : Part IV
In the previous part of this series, we discussed about few of the use cases. This is the Forth Part of Wearables and Internet of Things Series. In this part, we have disccused about usage in production and logistics, field service. Production and logistics Due to its flexibility and sensorimotor capabilities, humans will remain an important part of production and … [Read more...]
Serverless WordPress and Some Serverless WordPress Plugins
Serverless Probably One of the Most Tricky Usage of Cloud Computing. Serverless is the native architecture of the cloud that enables to shift the operational responsibilities to the cloud host without thinking about servers. Previously we discussed about Serverless, gave example how to work with IBM Serverless and published example of PHP scripts with Serverless. Also one can install Apache … [Read more...]
ESP32 Arduino : IBM Watson Visual Recognition of Images with cURL
IBM Watson Visual Recognition of Images Supports cURL. ESP32 Arduino Can Send cURL of Images and Receive JSON Response on Serial Monitor. Demo of Watson Visial Recognition can be found on this URL : [crayon-69fd2c3c5303d813621220/] WARNING : This testing project's Arduino/ESP32 code may return blank response at present. It is for pointing to understand how the platform can be used from … [Read more...]
WordPress Security : Apache2 Module to Log HTTP POST Method
Earlier we discussed about the HTTP POST method. Technically We Should Log HTTP Request Methods. Here is How to Apache Module to Log HTTP POST Method, As Example For WordPress Installation. After examination of few weeks log, we can block the malicious HTTP POST requests. This guide is for those who have installed Apache HTTPD server using our method. We say apache2 instead of apache to … [Read more...]
What is HTTP POST Method?
In some previous Arduino guide, we used HTTP POST method to upload sensor data. What is HTTP POST? HTTP POST is used to send data to a server to create or update a resource where the URL already existing. In the same way, we used HTTP GET with WordPress, HTTP PUT with OpenStack Swift. First, we need to understand what is HTTP POST, second we need to know basic difference with simillar methods such … [Read more...]
