Screen Scraping

What is Screen Scraping?

screen scraping is the process of extracting data from a graphical user interface (GUI) using a computer program. This can be done by identifying and capturing the elements of the GUI that contain the desired data, such as text, images, and buttons.

Screen scraping can be used for a variety of purposes, such as:

• Collecting data from legacy applications. Some legacy applications do not have APIs that can be used to extract data. Screen scraping can be used to extract data from these applications by capturing the data that is displayed on the screen.
• Completing tasks that are difficult or impossible to do manually. For example, screen scraping can be used to automate the process of filling out forms or submitting data to websites.
• Creating new applications or services. Screen scraping can be used to extract data from existing applications and websites to create new applications or services.

How Does it Work?

Screen scraping works by first identifying the elements of the GUI that contain the desired data. This can be done by using a variety of techniques, such as:

• Inspecting the HTML source code of the GUI. The HTML source code will contain information about the structure of the GUI and the elements that it contains.
• Using a screen scraping library. Screen scraping libraries provide tools that can be used to identify and capture elements of a GUI.

Once the desired elements of the GUI have been identified, they can be captured and extracted. This can be done by using a variety of techniques, such as:

• Taking screenshots of the GUI elements. The screenshots can then be processed to extract the desired data.
• Using a screen scraping library to capture the data directly from the GUI. Screen scraping libraries can typically capture text, images, and buttons from a GUI.

The extracted data can then be stored in a database or used in a new application or service.

Screen scraping is a powerful tool that can be used to extract data from a variety of sources. However, it is important to be aware of the legal and ethical implications of screen scraping. It is important to obtain permission from the owners of the GUI before scraping their data. Additionally, it is important to be careful not to overload the GUI with requests, as this can cause performance problems.

Is screen scraping legal?

Under PSD2 — the EU law designed to increase competition in the payments industry — screen scraping is still legal as long as certain security steps are followed, including identification of the TPP to the bank it is accessing. However, most banks have moved to providing APIs to enable access to account data and payments, so screen scraping is not necessary.

There has been plenty of debate on whether screen scraping should be banned entirely. In the UK, most banks provide APIs for access, and some banks that have supported screen scraping have now been required to transition to APIs. In Europe, the European Banking Authority (EBA) has advocated to end the practice, but industry consultations are still ongoing.

What’s the difference between open banking and screen scraping?

Open banking is a way of giving regulated companies secure, limited access to your bank account, with that customer’s permission. Previously, that information would only have been accessible by banks. Open banking has led to several examples of new and innovative services that help consumers and businesses make the most of their finances. Open banking can also include payment initiation, where TPPs make payments on behalf of their customers with their consent.

Screen scraping is effectively one way to power open banking. While other technologies are becoming more and more common, screen scraping is still accepted under PSD2 when more modern and secure API technology isn’t available or working.

Renewable Energy

 What is Renewable Energy?

Renewable energy uses energy sources that are continually replenished by nature—the sun, the wind, water, the Earth’s heat, and plants. Renewable energy technologies turn these fuels into usable forms of energy—most often electricity, but also heat, chemicals, or mechanical power.

Renewable energy refers to energy derived from naturally occurring and replenishable sources that are not depleted when used for electricity generation or other energy purposes. These sources of energy are considered sustainable because they are continuously available and do not contribute significantly to the depletion of finite resources or the emission of greenhouse gases. Renewable energy sources are often contrasted with non-renewable sources, such as fossil fuels (coal, oil, and natural gas), which are finite and produce harmful emissions when burned for energy.

Some common renewable energy sources include:

Solar Energy: Solar energy is harnessed from sunlight using photovoltaic cells (solar panels) to convert sunlight directly into electricity. It can also be used for heating water or spaces through solar thermal systems.

Wind Energy: Wind turbines capture the kinetic energy of the wind and convert it into electricity. Wind power is a rapidly growing source of renewable energy.

Hydropower (Hydroelectric Energy): Hydropower is generated by the movement of water, often in dams or flowing rivers. Turbines are used to convert the energy of moving water into electricity.

Biomass Energy: Biomass energy is derived from organic materials, such as wood, agricultural residues, and waste, which can be burned directly for heat or converted into biofuels like bioethanol and biodiesel.

Geothermal Energy: Geothermal energy harnesses the heat from within the Earth's crust to generate electricity or provide direct heating and cooling for buildings.

Tidal and Wave Energy: These forms of energy capture the kinetic energy of ocean tides and waves to generate electricity. They are less commonly used than other renewable sources due to technical and environmental challenges.
