Have you considered that plants and animals can get sick like us? Safeguarding their health is biosecurity.This resource is part of the Agricultural Cyberbiosecurity Education Resource Collection that contains resources for formal and non-formal agricultural educators working with middle school aged youth. Published as Open Educational Resources, all resources are provided in durable (pdf) and customizable (MS Word) formats. They are hosted on  GoOpenVA in a unique resource collection, Ag Cybersecurity Virginia Tech, at https://goopenva.org/curated-collections/143 and on on Virginia Tech’s stable repository, VTechWorks at https://doi.org/10.21061/cyberbiosecurity

With digitization, we see biosecurity, cybersecurity, and physical security begin to overlap. This overlap started a new discipline, cyberbiosecurity. This resource is part of the Agricultural Cyberbiosecurity Education Resource Collection that contains resources for formal and non-formal agricultural educators working with middle school aged youth. Published as Open Educational Resources, all resources are provided in durable (pdf) and customizable (MS Word) formats.

Steganography is the science and art of hiding messages in plain sight so only the sender and intended recipient know the existence of a message. Steganography can be characterized as security through obscurity. Through this lesson, students experience a portion of the engineering design process as they research steganography and steganographic methods; identify problems, criteria and constraints; brainstorm possible solutions; and generate ideas. These are the critical first steps in the engineering design process, often overlooked by students who want to get to the "doing" phases—designing, building and testing. In computer science, a thorough design phase makes program implementation much easier and more effective. Students obtain practice with a portion of the design process that may be less exciting, but is just as important as the other steps in the process.

Students apply the design process to the problem of hiding a message in a digital image using steganographic methods, a PictureEdit Java class, and API (provided as an attachment). They identify the problems and limitations associated with this task, brainstorm solutions, select a solution, and implement it. Once their messages are hidden, classmates attempt to decipher them. Based on the outcome of the testing phase, students refine and improve their solutions.
