Description:FIELD OF INVENTION
A scarecrow is a decoy or mannequin, often in the shape of a human. Humanoid scarecrows are usually dressed in old clothes and placed in open fields to discourage birds from disturbing and feeding on recently cast seed and growing crops. Scarecrows are used across the world by farmers, and are a notable symbol of farms and the countryside in popular culture. Scarecrow, device posted on cultivated ground to deter birds or other animals from eating or otherwise disturbing seeds, shoots, and fruit; its name derives from its use against the crow. The scarecrow of popular tradition is a mannequin stuffed with straw; free-hanging, often reflective parts movable by the wind are commonly attached to increase effectiveness.
BACKGROUND OF INVENTION
As our country’s subsistence farmers continue to encroach on natural ecosystems, the interaction between farmers and animals grows, resulting in conflicts. We investigated how raiding patterns fluctuate with different seasons, farm land, and crop varieties. A smart scarecrow system has been proposed here to minimize crop raiding and man animal conflict from wild animals and birds. The scaring system works in three parts, such as object detection, message sending, and automatic height adjustment. Object detection is done by the PIR sensor and preventive action has been taken by initiating a servo, speaker, and blinking light. After object detection, alert will be sent by IoT cloud to the farm owner. Depending upon seasonal cropping, the pattern height of the system gets automatically adjusted by using motor, string pulley, and sliding drawer mechanism after the activation of ultrasonic sensor. The proposed study obtains the samples from different farms that are combined and observed how the object detection vary day and night in three seasons in order to provide the overall system efficiency. It is more convenient and cost effective than traditional scaring strategies like trapping, hunting, and wood fencing. The present system is made up of metal body, which does not require any manpower and at the same time, it can work under any worst climate conditions.

LITURATURE SURVEY
Jialong Zhang, “Scarecrow: Deactivating Evasive Malware via Its Own Evasive Logic”; Security analysts widely use dynamic malware analysis environments to exercise malware samples and derive virus signatures. Unfortunately, malware authors are becoming more aware of such analysis environments. Therefore, many have embedded evasive logic into malware to probe execution environments before exposing malicious behaviors. Consequently, such analysis environments become useless and evasive malware can damage victim systems with unforeseen malicious activities. However, adopting evasive techniques to bypass dynamic malware analysis is a double-edged sword. While evasive techniques can avoid early detection through sandbox analysis, it also significantly constrains the spectrum of execution environments where the malware activates. In this paper, we exploit this dilemma and seek to reverse the challenge by camouflaging end-user execution environments into analysis-like environments using a lightweight deception engine called SCARECROW. We thoroughly evaluate SCARECROW with real evasive malware samples and demonstrate that we can successfully deactivate 89.56% of evasive malware samples and the variants of ransomware (e.g., WannaCry and Locky) with little or no impact on the most commonly used benign software. Our evaluation also shows that SCARECROW is able to steer state-of-the-art analysis environment fingerprinting techniques so that end-user execution environments with SCARECROW and malware analysis environments with SCARECROW become indistinguishable. Keita Higuchi, “Scarecrow: Avatar Representation Using Biological Information Feedback”; Scarecrow is an avatar representation method that uses biological information to improve the immersive experience. Traditional computer games and virtual reality (VR) environments focus on operability and the immersive experience. Controller devices are used to communicate from the real world with the virtual world. The usability of control methods affect the immersive experience of the users. Recently, many of these VR environments have adopted motion sensors (e.g. Microsoft Kinect sensors) Motion sensors can measure the user's movements and gestures to input control parameters for the virtual world and a self-avatar. Motion sensor-based games can help users to become more active and take steps to advance their health. Biological information, such as heart rate, body temperature, and muscle fatigue change depending on exercise volume. In this paper, we use a real-time biological information feedback to synchronize the user and the avatar representation. For instance, the color of the avatar changes according to the skin temperature of the user's face. We hypothesize that this representation method will motivate user activities, and improve the immersive experience. We implement a Scarecrow prototype using a streaming server for measurements of the user's behaviors and a front-end exercise game. We also perform an early user study to report the user experience and discuss the effects of the proposed method. We discuss the potential of the Scarecrow, which might encourage human exercise activities, and control human biological information.

SUMMARY
A Scarecrow is normally used by farmers to save the crops from the birds and animals in the field. Scarecrow helps to the farmers to save their crops by scare of the birds and animals. In village, Scarecrow is made by using the old cloths and sticks and give it to a scary look to scare the birds and animals to the crops of the farmers. Scarecrow is also used in gardens and at the Airports. A Scarecrow does not effective in the night to provide the security for the crops. So there is an option of using Automatic Scarecrow instead of using Normal Scarecrow. Automatic Scarecrow can also be called as Smart Scarecrow. An Automatic Scarecrow or Smart Scarecrow is more efficient than a Normal Scarecrow. Automatic Scarecrow provides all time security to the crops from the birds and animals. It is effective in both Day and Night. It works Automatically. Automatic Scarecrow is equipped with Sensors, Movable Arms and alarming device. We have seen that scarecrow has no movement when the birds are come in field. In our project we are going to modify this scarecrow that when the birds come in the field, it will sense the coming of birds with the help of PIR Sensor and move its hand Up and Down with the help of Flapping mechanism and it will start ringing with the help of Buzzer, The aim of the flapping mechanism is to convert the rotary motion of the motor into the linear motion of flapping hands. when the crank rotates, the connecting rods pushes the hand up and down .it will help to scare the birds and the birds will be run away from the field and the crop of the field will become safe. It can also be used in Garden.
