A system and method for displaying a glyph on a graphical user interface to protect the displayed glyph against eavesdropping. The method comprises providing multiple frames of the glyph, each frame representing a partial glyph which includes at least one component of the glyph. The multiple frames of the glyph may be displayed successively, at a predetermined frequency, on the graphical user interface so that a user observes the glyph by visually integrating the successive multiple frames of partial glyphs. The glyph may be a combination of glyphs including characters, keys or images which may represent an onscreen keyboard or keypad. The glyph may be moved across the graphical user interface and may further be obfuscated.
